Apple has a blockchain iOS and OSX app. They have bitcoin tickers and chart apps. So why is everyone hating on Apple?

I have the Blockchain iOS app on my phone, and have the Blockchain OSX Desktop app.
There are plenty of mining applications for those who need them... so whats with all the hating on Apple? What more do you need?

[ANN][ANDROID MINING][AIRDROP] NewEnglandcoin: Scrypt RandomSpike

New England
New England 6 States Songs: https://www.reddit.com/newengland/comments/er8wxd/new_england_6_states_songs/
NewEnglandcoin
Symbol: NENG
NewEnglandcoin is a clone of Bitcoin using scrypt as a proof-of-work algorithm with enhanced features to protect against 51% attack and decentralize on mining to allow diversified mining rigs across CPUs, GPUs, ASICs and Android phones.
Mining Algorithm: Scrypt with RandomSpike. RandomSpike is 3rd generation of Dynamic Difficulty (DynDiff) algorithm on top of scrypt.
1 minute block targets base difficulty reset: every 1440 blocks subsidy halves in 2.1m blocks (~ 2 to 4 years) 84,000,000,000 total maximum NENG 20000 NENG per block Pre-mine: 1% - reserved for dev fund ICO: None RPCPort: 6376 Port: 6377
NewEnglandcoin has dogecoin like supply at 84 billion maximum NENG. This huge supply insures that NENG is suitable for retail transactions and daily use. The inflation schedule of NengEnglandcoin is actually identical to that of Litecoin. Bitcoin and Litecoin are already proven to be great long term store of value. The Litecoin-like NENG inflation schedule will make NewEnglandcoin ideal for long term investment appreciation as the supply is limited and capped at a fixed number
Bitcoin Fork - Suitable for Home Hobbyists
NewEnglandcoin core wallet continues to maintain version tag of "Satoshi v0.8.7.5" because NewEnglandcoin is very much an exact clone of bitcoin plus some mining feature changes with DynDiff algorithm. NewEnglandcoin is very suitable as lite version of bitcoin for educational purpose on desktop mining, full node running and bitcoin programming using bitcoin-json APIs.
The NewEnglandcoin (NENG) mining algorithm original upgrade ideas were mainly designed for decentralization of mining rigs on scrypt, which is same algo as litecoin/dogecoin. The way it is going now is that NENG is very suitable for bitcoin/litecoin/dogecoin hobbyists who can not , will not spend huge money to run noisy ASIC/GPU mining equipments, but still want to mine NENG at home with quiet simple CPU/GPU or with a cheap ASIC like FutureBit Moonlander 2 USB or Apollo pod on solo mining setup to obtain very decent profitable results. NENG allows bitcoin litecoin hobbyists to experience full node running, solo mining, CPU/GPU/ASIC for a fun experience at home at cheap cost without breaking bank on equipment or electricity.

CPU Minable Coin Because of dynamic difficulty algorithm on top of scrypt, NewEnglandcoin is CPU Minable. Users can easily set up full node for mining at Home PC or Mac using our dedicated cheetah software.
Research on the first forked 50 blocks on v1.2.0 core confirmed that ASIC/GPU miners mined 66% of 50 blocks, CPU miners mined the remaining 34%.
NENG v1.4.0 release enabled CPU mining inside android phones.

Decentralization and Community Driven NewEnglandcoin is a decentralized coin just like bitcoin. There is no boss on NewEnglandcoin. Nobody nor the dev owns NENG.
We know a coin is worth nothing if there is no backing from community. Therefore, we as dev do not intend to make decision on this coin solely by ourselves. It is our expectation that NewEnglandcoin community will make majority of decisions on direction of this coin from now on. We as dev merely view our-self as coin creater and technical support of this coin while providing NENG a permanent home at ShorelineCrypto Exchange.

ASIC/GPU Mining Pools Warning to Big ASIC Miners Due to DynDiff Algo on top of Scrypt, solo mining is recommended for ASIC/GPU miners. Further more, even for mining pools, small mining pool will generate better performance than big NENG mining pool because of new algo v1.2.x post hard fork.
The set up configuration of NENG for scrypt pool mining is same as a typical normal scrypt coin. In other word, DynDiff on Scrypt algo is backward compatible with Scrypt algo. Because ASIC/GPU miners rely on CPU miners for smooth blockchain movement, checkout bottom of "Latest News" section for A WARNING to All ASIC miners before you decide to dump big ASIC hash rate into NENG mining.
(1) Original DynDiff Warning: https://bitcointalk.org/index.php?topic=5027091.msg48324708#msg48324708 (2) New Warning on RandomSpike Spike difficulty (244k) introduced in RandomSpike served as roadblocks to instant mining and provide security against 51% attack risk. However, this spike difficulty like a roadblock that makes big ASIC mining less profitable. In case of spike block to be mined, the spike difficulty immediately serve as base difficulty, which will block GPU/ASIC miners effectively and leave CPU cheetah solo miners dominating mining almost 100% until next base difficulty reset.

Complete Guide to the Eidoo App

One of the most popular multi-currency wallets: here is our complete guide to Eidoo
Eidoo is a multi-currency wallet available for Android and iOS. A widely announced Desktop version (OSX, Windows and Linux) has been available for some time now and is finally stable. It currently supports Bitcoin, Ethereum, ERC20 and ERC223 tokens, and numerous other cryptocurrencies.
Very easy to use app, it provides a high level of security and a hybrid exchange inside the application. Our complete guide to Eidoo will mainly cover the Android version with some references to the desktop version.

Almost all ICOs are designed using the Ethereum blockchain and the related tokens are based on the ERC-20 standard.
ERC-20 is the standard used for smart contracts on the Ethereum blockchain and defines a set of rules for the implementation of tokens within the network itself.
You will therefore need a compatible wallet to send the tokens earned through Airdrops or purchased in the pre-ICO phase in case you do not want to move them to the exchange on which they will be exchanged.


In our opinion, Eidoo is the wallet par excellence for these digital coins and in this guide we will explain in detail how to use it as well as provide further details and news on its various ecosystem.

The first time with Eidoo.
1- Download the app from the Reactive Store at the S.O. of your smartphone or at the following link: https://eidoo.io/

Complete Guide Eidoo
2– Once started you have to choose whether to create a new wallet - in the case of the first use - or recover an existing wallet.


3 - Enter the password you will need to access the application on your device and confirm "terms and conditions".

Complete Guide Eidoo
4 - In the next screen select BACK NOW and re-enter the password to access the 12 words of the PASSPHRASE. If you want to recover your previous wallet, the RESTORE screen will appear (IMG 6b).


Complete Guide Eidoo

5 - Make a note of these 12 words somewhere as only thanks to these will you be able to recover the contents of your wallet in case your device is lost or the PC hard disk fails. On the next screen, enter them in the order listed.

Complete Guide Eidoo

6 - Here we are inside your personal wallet. By clicking on the top right, your Ethereum address will appear on which to receive the coin and tokens. Click on one of them and access the information screen (IMG 13). Pressing TRANSFER at the bottom will open a further screen where you can enter the destination Ethereum address and the amount to be transferred. Click on Advanced to establish the amount of Gas (Ether) to be used according to the urgency of the transfer (IMG 14).


It is possible to make a quick swap between cryptocurrencies, a bit like it happens on Coinbase, or buy them by credit card or bank transfer.

Complete Guide Eidoo

Let's now go deeper into the Eidoo App.
7 - Let's now access the menus below. Exchange is now active and you can exchange various tokens with each other directly within the application. Through the Trading Wallet you will first have to move the cryptocurrencies you wish to dedicate to trading from your Personal Wallet to the Eidoo Hybrid Exchange. Trading fees are unfortunately quite high.


Complete Guide Eidoo

8 - Eidoo Crowd. Shows a list of ICOs supported by Eidoo that you can participate in after evaluating the opportunity.


9 - More. In this section you can:

a) connect to your account on the Eidoo website for data verification

b) back up the wallet and change the Password

c) save the most used Ethereum and Bitcoin addresses

d) select the desired language

e) select the traditional reference currency

f) show hidden assets

g) add an unknown token. Force token enrollment will be used in the event that your tokens appear on Etherscan.io without being able to see them in your wallet. By entering the address of the smart contract (on how to use etherscan and smart contracts we invite you to read our Guide to Airdrops) you can insert them in your wallet.

h) enable notifications

i) share usage data anonymously

l) reset the application (you will not lose your tokens)

m) Send a report if there is a problem with the application

Desktop version 2.1.4

Complete Guide Eidoo


9 - Finally, by clicking on the Eidoo icon at the bottom center, a screen will open that will show the amount of your Edo, the Eidoo token.


10 - Every time you access Eidoo, even if it is not actually closed but placed in the background, you must enter the password.


See you soon for the next guide!

Introduction to The Quantum Resistant Ledger

Overview
Introduction
Quantum computers, which have at times been dismissed as a physical impossibility, have gone from the realm of "if" to the realm of "when" over the last decade.
QRL was early to recognize the threat quantum computers posed, not just to data security of the world, but blockchain as well. In response, we created a fully open source (MIT)[1], independently audited[2,3], blockchain platform[4,5], secure against even an attack from quantum computers[6].
With security as a foundation, we've developed a feature rich platform with things like notarization[7], multisig transactions[8], and an Ephemeral Messaging System[9]. This is all done with performance[10] in mind to handle volumes expected of any enterprise-grade blockchain. Future developments include Smart Contracts, and PoS.
QRL is backed by the research of individuals, organizations and institutions, with citations from several[11]. We are commited to the scientific philosophy to development with 3 open research grants[12].

Is blockchain really at risk of Quantum Computing?
In short, it's not a matter of if, but when quantum computing is capable of breaking ECDSA P-256 (what Bitcoin, Ethereum and most blockchain projects use). We've put together a site called Frequently Asked Quantum Questions which has plenty of sources and should answer many of your questions: https://faqq.info/.
Worth a read is a multipart series put together by one of our community members, QRCollector.

Now heres the thing. The first two sorta kinda applies to me but what i dont understand is why now. Obviously I no longer do this, its been like years since i've did such thing. So an certain individual had falsely mass reported me on periscope for the reason spam. Twitter sees it as "platform manipulation and spam". And then I later receive this email from three of my twitter account's emails saying "Artificially inflating your own or others’ followers or engagement is a violation of the Twitter Rules". I just find this really weird and odd. The reason of account transfers or sales doesnt apply to me because i never bought or sold these accounts to anyone. Reciprocal inflation, im guessing follow trains and such? I guess i have participated in some of those by retweeting others tweets but i havent like made any tweets asking for followforfollow or retweetforretweets.

Selling/purchasing Tweet or account metric inflation - I dont sell any account metric inflation. As for purchasing, a while ago i believe i tried to buy like 1k for like five dollars or something just to try it out but like its been years. There was a site that i had used once in a while but eventually stopped called Youlikehits . Stated on their website:
Only Follow, Like, Subscribe, Share or Visit who and what you're interested in! We don't sell Followers, Likes, Subscribers, Shares or Hits. We are not a follow/like exchange. We never post from your Accounts without your permission. We don't ask for your account passwords. We have a strict NO Bot/Macro/Automation policy. All followers/likes/views are from real people. 
apps – using or promoting third-party services or apps that claim to add followers or add engagements to Tweets.
heres a list of apps currently connected to one of my twitter accounts
Squarespace Tippin.me - some bitcoin tipping service OSX - twitter on Mac Periscope Web Tiktok iOS - twitter for iOS MTV music awards vote PUBG Mobile Rockstar games social club Gofundme Yelp Unfollowspy - monitor and analyze followers and following. Located inactive and spam followers MARIO Kart Tour Audit and block fake followers - finds out how many of my followers are real Hypixel rewards Gleam competition app - a site used to grow your business. Most of the time is used in giveaways and such. Crowdfire - social media management. Discover and schedule content. Unlimapps - third party app that also for developers to add their own features to certain apps. Instagram - Niche - provides creators with the ability to grow, understand, and activate their social presence across all networks Swift key personalization Spotify Amazon Who followed me- makes it easy to track unfollowers as well as new followers. People who don’t follow back and people I don’t follow back. Giving the options to unfollow or follow as I see fit Tweepi- allows you to find relevant users on twitter, while being able to get a better understanding of your followers and friends. Blocktogether - a web app intended to help cope with harassment and abuse on twitter (no longer works as of 2018-06-28 Twitterific for IOS Siri Hive for Twitter- helps brands send emails they can feel good about. Super Mario run Vine Stripe Vine web SoundCloud Tweetdeck Unfollowerstats.com - track and unfollow your followers Periscope Mobile web - twitter. 
Tbh I didn’t even know I had this many apps connected but like these Twitter management tools are used to help mangage my followers and following and such.
If anyone has any encounters with this similar email, please let me know down below your stories and how you appealed it.

Groestlcoin 6th Anniversary Release

Introduction

Dear Groestlers, it goes without saying that 2020 has been a difficult time for millions of people worldwide. The groestlcoin team would like to take this opportunity to wish everyone our best to everyone coping with the direct and indirect effects of COVID-19. Let it bring out the best in us all and show that collectively, we can conquer anything.
The centralised banks and our national governments are facing unprecedented times with interest rates worldwide dropping to record lows in places. Rest assured that this can only strengthen the fundamentals of all decentralised cryptocurrencies and the vision that was seeded with Satoshi's Bitcoin whitepaper over 10 years ago. Despite everything that has been thrown at us this year, the show must go on and the team will still progress and advance to continue the momentum that we have developed over the past 6 years.
In addition to this, we'd like to remind you all that this is Groestlcoin's 6th Birthday release! In terms of price there have been some crazy highs and lows over the years (with highs of around $2.60 and lows of $0.000077!), but in terms of value– Groestlcoin just keeps getting more valuable! In these uncertain times, one thing remains clear – Groestlcoin will keep going and keep innovating regardless. On with what has been worked on and completed over the past few months.

UPDATED - Groestlcoin Core 2.18.2

This is a major release of Groestlcoin Core with many protocol level improvements and code optimizations, featuring the technical equivalent of Bitcoin v0.18.2 but with Groestlcoin-specific patches. On a general level, most of what is new is a new 'Groestlcoin-wallet' tool which is now distributed alongside Groestlcoin Core's other executables.
NOTE: The 'Account' API has been removed from this version which was typically used in some tip bots. Please ensure you check the release notes from 2.17.2 for details on replacing this functionality.

How to Upgrade?

ALL NEW - Groestlcoin Moonshine iOS/Android Wallet

Built with React Native, Moonshine utilizes Electrum-GRS's JSON-RPC methods to interact with the Groestlcoin network.
GRS Moonshine's intended use is as a hot wallet. Meaning, your keys are only as safe as the device you install this wallet on. As with any hot wallet, please ensure that you keep only a small, responsible amount of Groestlcoin on it at any given time.

ALL NEW! – HODL GRS Android Wallet

HODL GRS connects directly to the Groestlcoin network using SPV mode and doesn't rely on servers that can be hacked or disabled.
HODL GRS utilizes AES hardware encryption, app sandboxing, and the latest security features to protect users from malware, browser security holes, and even physical theft. Private keys are stored only in the secure enclave of the user's phone, inaccessible to anyone other than the user.
Simplicity and ease-of-use is the core design principle of HODL GRS. A simple recovery phrase (which we call a Backup Recovery Key) is all that is needed to restore the user's wallet if they ever lose or replace their device. HODL GRS is deterministic, which means the user's balance and transaction history can be recovered just from the backup recovery key.

ALL NEW! – GroestlcoinSeed Savior

Groestlcoin Seed Savior is a tool for recovering BIP39 seed phrases.
This tool is meant to help users with recovering a slightly incorrect Groestlcoin mnemonic phrase (AKA backup or seed). You can enter an existing BIP39 mnemonic and get derived addresses in various formats.
To find out if one of the suggested addresses is the right one, you can click on the suggested address to check the address' transaction history on a block explorer.

ALL NEW! – Vanity Search Vanity Address Generator

NOTE: NVidia GPU or any CPU only. AMD graphics cards will not work with this address generator.
VanitySearch is a command-line Segwit-capable vanity Groestlcoin address generator. Add unique flair when you tell people to send Groestlcoin. Alternatively, VanitySearch can be used to generate random addresses offline.
If you're tired of the random, cryptic addresses generated by regular groestlcoin clients, then VanitySearch is the right choice for you to create a more personalized address.
VanitySearch is a groestlcoin address prefix finder. If you want to generate safe private keys, use the -s option to enter your passphrase which will be used for generating a base key as for BIP38 standard (VanitySearch.exe -s "My PassPhrase" FXPref). You can also use VanitySearch.exe -ps "My PassPhrase" which will add a crypto secure seed to your passphrase.
VanitySearch may not compute a good grid size for your GPU, so try different values using -g option in order to get the best performances. If you want to use GPUs and CPUs together, you may have best performances by keeping one CPU core for handling GPU(s)/CPU exchanges (use -t option to set the number of CPU threads).

Groestlcoin EasyVanity 2020 is a windows app built from the ground-up and makes it easier than ever before to create your very own bespoke bech32 address(es) when whilst not connected to the internet.
If you're tired of the random, cryptic bech32 addresses generated by regular Groestlcoin clients, then Groestlcoin EasyVanity2020 is the right choice for you to create a more personalised bech32 address. This 2020 version uses the new VanitySearch to generate not only legacy addresses (F prefix) but also Bech32 addresses (grs1 prefix).

ALL NEW! – Electrum Personal Server

Groestlcoin Electrum Personal Server aims to make using Electrum Groestlcoin wallet more secure and more private. It makes it easy to connect your Electrum-GRS wallet to your own full node.
It is an implementation of the Electrum-grs server protocol which fulfils the specific need of using the Electrum-grs wallet backed by a full node, but without the heavyweight server backend, for a single user. It allows the user to benefit from all Groestlcoin Core's resource-saving features like pruning, blocks only and disabled txindex. All Electrum-GRS's feature-richness like hardware wallet integration, multi-signature wallets, offline signing, seed recovery phrases, coin control and so on can still be used, but connected only to the user's own full node.
Full node wallets are important in Groestlcoin because they are a big part of what makes the system be trust-less. No longer do people have to trust a financial institution like a bank or PayPal, they can run software on their own computers. If Groestlcoin is digital gold, then a full node wallet is your own personal goldsmith who checks for you that received payments are genuine.
Full node wallets are also important for privacy. Using Electrum-GRS under default configuration requires it to send (hashes of) all your Groestlcoin addresses to some server. That server can then easily spy on your transactions. Full node wallets like Groestlcoin Electrum Personal Server would download the entire blockchain and scan it for the user's own addresses, and therefore don't reveal to anyone else which Groestlcoin addresses they are interested in.
Groestlcoin Electrum Personal Server can also broadcast transactions through Tor which improves privacy by resisting traffic analysis for broadcasted transactions which can link the IP address of the user to the transaction. If enabled this would happen transparently whenever the user simply clicks "Send" on a transaction in Electrum-grs wallet.
Note: Currently Groestlcoin Electrum Personal Server can only accept one connection at a time.

UPDATED – Groestlcoin Sentinel 3.5.06 (Android)

Groestlcoin Sentinel is a great solution for anyone who wants the convenience and utility of a hot wallet for receiving payments directly into their cold storage (or hardware wallets).
Sentinel accepts XPUB's, YPUB'S, ZPUB's and individual Groestlcoin address. Once added you will be able to view balances, view transactions, and (in the case of XPUB's, YPUB's and ZPUB's) deterministically generate addresses for that wallet.
Groestlcoin Sentinel is a fork of Groestlcoin Samourai Wallet with all spending and transaction building code removed.

BitPay is f*cking up bitcoins adoption

I tried to buy a simple domain with bitcoin today on namecheap.com using BitPay just to check out how smooth the whole payment process is.

After clicking on namecheap's 'PURCHASE NOW' button, a mysterious looking BitPay popup occurred. I entered my email just in case I needed a refund, clicked on continue and this is what I got: https://imgur.com/Q9xMIYR

Well, I was using the blockchain.info wallet in a google chrome OSX Browser and I had no way to scan this QR code. They just fapped a QR Code right into this shit hole and thought it was okay to let the desktop users rot in hell. Seriously, WHY IS IT SO HARD TO PROVIDE AN ADDRESS? Fuck off with your 'Make it simple and intuitive' approach. B*tch just give me an address so I can quickly copy it in my wallet. Who in his right mind thought it was okay to ship a product like this to the mass? AHHHH....

Anyways, I clicked on the 'Open in Wallet' button, checked my blockchain.info tab and nothing happened. I repeated this step numerous times, but the result was always the same and it was clear to me that I had to download the blockchain.info mobile app to scan the QR code, because yeah, bitgay wants to be smart and thought adding a simple address is not good enough.

At this time I was already pissed but I downloaded the mobile app anyways just to try it out. Scanned the code and an error occurred. Well, after researching a bit, I found out that bitpay only accepts 'Payment Protocol-compatible' wallets and blockchain.info, one of the biggest or even the biggest wallets, is not one of them. Why did nobody tell me this? Bitpay, why is it so hard to tell this to your customers? Why do I have to waste my fucking time and destroy my joy of using bitcoin?

I ended up purchasing the domain with paypal. This took me 5 seconds.

Thanks for fucking this up BitPay.

#BoycottBitpay

tldr;
bitpay sucks
forces users to use specific wallets that comply with their bullshit
newbies don't know shit and are getting annoyed af
f*ck them up

Best Ethereum Wallets

Best Ethereum Wallets
When you start using cryptocurrency the number one problem is to find a secure wallet. In this article, we will introduce the most popular Ethereum wallets.

Hardware Wallets

We start with hardware wallets. These wallets provide offline storage for cryptocurrency. This kind of Ethereum wallet is considered to be the most secure.
https://preview.redd.it/86nocaff0mh31.jpg?width=720&format=pjpg&auto=webp&s=7a6d4e9a4ef9945eec416583d487e5553c4377e9

  • Trezor
Originally Trezor was developed for Bitcoin. Now it supports more different cryptocurrencies including Ethereum. This ETH wallet will work in tandem with your MyEtherWallet.Trezor is famous for the features that make it very secure. It provides 2-factor authentication, advanced cryptography and the opportunity to check transaction details before you confirm.
On the other hand, there are a couple of disadvantages. Such as the cost: the Trezor wallet is pretty expensive. If you are not a regular user you probably should consider cheaper wallets. Also, it takes time to access your holdings with this wallet.Thus using Trezor as Ethereum wallet may be a little inconvenient if you are a common user.

  • Ledger Nano S
Ledger Nano S is also a hardware wallet. It connects with any computers via USB. The most important feature of this wallet is security. As well as Trezor it provides 2-factor authentication. Aside from this, this Ethereum wallet has a PIN code to secure the device itself and also you can back up your account on the recovery sheet. Ledger Nano S gives users an opportunity to check details of transactions before the confirmation.
The main disadvantage of the Ledger Nano S wallet is the price. It is cheaper than Trezor, but it is still pricey.

  • KeepKey
KeepKey is a hierarchical deterministic (HD) wallet. It is also in the group of hardware wallets. KeepKey supports a lot of cryptocurrencies.The fact that this is an HD wallet allows users to generate private keys in an unlimited quantity. Undoubtedly this adds to the security level. Moreover, with the help of this device, you review and confirm every transaction. You can also set up a PIN code and a recovery sentence to make sure your holdings are secured enough.
It is easy to start using the KeepKey wallet. You need to download a couple of applications. One is to create a wallet. And with the help of the second one, you will be able to connect to KeepKey through Chrome.
Talking about the disadvantages we should mention the price. It is one of the most expensive wallets on the market to use it as ETH wallet.

Web Wallets

The great thing about web wallets is that you can easily access them. All you need is an internet connection.

  • MyEtherWallet
Unlike the most part of hardware wallets, MyEtherWallet is free. Nonetheless, it provides a high level of security by allowing users to store their keys on their own computers. There is no necessity to give any private information when creating a wallet.This Ethereum wallet interrogates with some hardware wallets such as Ledger Nano S and Trezor. Also, this platform gives an opportunity to write smart contracts.
In addition, MyEtherWallet provides automatic back up. So users should not remember about this by themselves.Moreover, it’s possible to get a paper Ethereum wallet by going to the “Wallet Info” section.
https://preview.redd.it/j7wzg5ki0mh31.png?width=1088&format=png&auto=webp&s=41383744e961877ba6acbf128be7fdcb2f4baf77

  • Coinbase
First of all, Coinbase is an exchange platform. Usually, it is not recommended to store cryptocurrency on the stock platforms. But Coinbase is often considered to be an exception. This platform has a wallet that is suitable for use as ETH wallet. It is easy to use and has an intuitive interface.
One of the major drawbacks of this wallet is that users don’t control their private keys.

  • MetaMask
MetaMask is not just a popular Ethereum wallet. It is a browser extension. It can be installed on a number of browsers such as Chrome, Firefox, and Opera. This form allows accessing your holdings easily.The good thing is that you don’t need to provide personal information for the registration. Also, there is an opportunity to store the private key on your computer.

Desktop Wallets

There are wallets that are made in the form of a software program. They can be installed on your device. Such wallets are called Desktop Wallets.The security level of these wallets is not as good as of hardware ones.

  • Exodus
Exodus is a multicurrency wallet. So it can become your ETH wallet.It is famous for its user-friendly interface. It is a good wallet for those who only start their journey into the cryptocurrency world. Exodus supports ERC20 tokens.Users store their private keys on their computers. This increases the security level. Exodus has a backup feature.
The drawbacks of Exodus are that there is no possibility to add any custom tokens and a small list of ERC20 tokens.

  • Atomic Wallet
Atomic Wallet has a very convenient interface which is suitable even for the beginners. It supports Ethereum and all the ERC20 tokens.The wallet supports atomic swaps. So you can not only have one wallet for Ethereum and all the ERC20 tokens but also exchange them with another user.
Unfortunately, it doesn’t have a hardware wallet yet. So the level of security may not be very high.

https://preview.redd.it/e13whvvl0mh31.png?width=1024&format=png&auto=webp&s=8ee93d65adfcee76b0f8043c6ae1e4c022c16c0b

  • Mist
Mist is the official Ethereum wallet. So it is a full node wallet. Full node wallet downloads the whole Ethereum blockchain on users’ computers. In other words, it downloads all the data about the ETH network. This type of wallet makes any user a full-fledged member of the blockchain.
Mist has developed the way to allow users to interact with their ETH storage easily. It is free. Users don’t provide private information during the process of registration. The only way to access your wallet is to use a password. Your private keys are stored on your computer.The Mist wallet supports smart contracts.

Mobile Wallets

Sometimes it is more convenient to use a mobile wallet, which can be installed on your mobile devices. This type of wallets provides quicker access to your storage wherever you are. Mobile wallets are easier to use than desktop ones, but it is riskier.

  • Jaxx Liberty
Jaxx is free. It supports a lot of cryptocurrencies including ETH. It can work on different platforms such as Linux, Windows, and OSX. There is also an extension for Chrome browser. The interface of Jaxx wallet is simple and good to use.
However, the security of this wallet raises some questions.

  • Coinomi
Coinomi is an Android app. It is easy to use and supports a wide range of cryptocurrencies. With this wallet, you don’t have to think about backup. Coinomi has a feature that helps you to keep all the information. It is secure enough. Your private keys are nowhere but on your device. Coinomi protects the user’s identity when they sign up.
Unfortunately, so far there is only an app for Android.

https://preview.redd.it/4iyn26do0mh31.png?width=1604&format=png&auto=webp&s=7a9d58bb81911aa336aa93320dbdae5f763d4a3e

Paper Wallets

Paper wallets allow printing private keys on paper. And this printed document is used as a wallet. These wallets are not that easy to access. Although the level of security is relatively high.

  • ethaddress
In case you are looking for a way to store your ETH in the most secure Ethereum wallet, but you are not ready to pay for a hardware one, try ethaddress. This wallet is free. It provides a high level of security.

  • WalletGenerator.net
The core of this key-generating wallet is 99% identical to the well-considered bitaddress.org.First of all, it’s necessary to download this website from Github, unpack and open the index.html file directly from your computer. The code version control allows to significantly simplify the mutual verification of the executable code. For more security, disconnect from the Internet at the time of creating your wallet.

How to keep your wallet in security?

Whatever wallet you choose you want it to be as secure as possible. Here are some ideas on how to achieve this:
  • Choose a wallet that suits your requirementsAll wallets are aimed at different goals and ways to use. Some of these wallets offer high security, some provide you with easy access for fast trading. Therefore, you should choose exactly what suits your needs best.
  • Keep your private key safeAlways make sure that your private key is secure and is stored in a safe place. Moreover, do not share your private keys. No, not with friends. Not even with your parents.
  • Set up 2-factor authenticationSome wallets offer this feature to increase the security of your coins. Do not ignore 2-factor authentication, set it up for extra confidence in protection against theft.
  • Backup, backup, and backupNothing protects you better from unforeseen accidents than a good old backup. This way you can keep access to your coins.
  • Store your funds offlineWith all the security levels offline wallets are still the most secure ones. Therefore, it is better to keep large amounts of ETH coins only on offline wallets.

SKIP TO THE BOTTOM FOR FREE MONEY
Hi, my name is BitAlien, and I'd like to teach you a little bit about Bitcoin Cash.
You've probably heard of Bitcoin before. Bitcoin was the world's first Peer-to-Peer Electronic Cash System. With Bitcoin, you can send any amount of money to anyone in the world without anyone's permission. Governments cannot censor Bitcoin transactions. No company "owns" the Bitcoin network. Bitcoin is decentralized and permissionless.
Bitcoin transaction fees used to cost less than a cent. Compared to the legacy banking system where transactions can cost hundreds of dollars, this was a huge improvement. As you can see, Bitcoin is a revolutionary technology.
Unfortunately, Bitcoin's development was subverted by Blockstream, a company which employs many "Bitcoin Core" developers to create changes to the Bitcoin software which benefits them. These Core developers have openly admitted that high fees are a good thing, and want to turn Bitcoin into a settlement layer, moving the majority of transactions onto lightning networks. (The technology that Blockstream just happens to specialize in)
Bitcoin Cash is a fork of the Bitcoin blockchain that was created on August 1st 2017. Bitcoin Cash aims to solve Bitcoin's scaling problems, follow Satoshi's original vision, and allow users to once again create transactions with low fees.
Reliable, frictionless money like Bitcoin Cash will change the world's economy for the better.
Bitcoin Cash Wallet Recommendations:
Today I'm giving $1 away to everyone interested, so that you can personally experience this awesome new technology!
Reddit requirements: 7 day old account minimum, 50 karma minimum
Twitter requirements: 1 month old account minimum
If on Reddit, create a comment replying to this post with your Bitcoin Cash address. I will send you $1! :)
If on Twitter, retweet so more people can see this giveaway, and then reply to my original tweet with your Bitcoin Cash address. I will send you $1! :)
We are going to show people the power of Bitcoin Cash! :D

Losing faith in ledger

EDIT: Finally got it working on the 4th cable. Seems a Blackberry cable makes it work if anyone runs into the same issue. Thanks for everyone's help
Got my nano S in the mail after a month of waiting. Set it up and no computer will recognize it at all. Tried everything suggested in the support forum and on reddit. So opened a ticket. The only responses I’ve received have been asking me if I still want help and a form response asking for an error code. The link on the chrome ledger manager for help leads to a non-existent page, and the link in their support forum leads to a page that I’m not authorized to view.
Don’t know what else to do now than to wait for another response from the support team.
I know people have been having issues with their computers recognizing the wallet, but have they been resolved by ledger?

Bitcoin Cash tipping MEGATHREAD - Receive $3 of BCC and introduce two of your friends to it!

That's it for now! About $400 worth of BCC was given out. Thanks for spreading the word!
You've probably heard of Bitcoin before. Bitcoin was the world's first Peer-to-Peer Electronic Cash System. With Bitcoin, you can send any amount of money to anyone in the world without anyone's permission. Governments cannot censor Bitcoin transactions. No company "owns" the Bitcoin network. Bitcoin is decentralized and permissionless.
Bitcoin transaction fees used to cost less than a cent. Compared to the legacy banking system where transactions can cost hundreds of dollars, this was a huge improvement. Bitcoin is a revolutionary technology.
Unfortunately, Bitcoin's development was subverted by Blockstream, a company which employs many "Bitcoin Core" developers. Blockstream exists to cripple Bitcoin by stalling progress e.g. introducing extremely complicated changes like SegWit, and keeping the block size limit at 1 MB so that more people cannot use Bitcoin.
Bitcoin Cash is a fork of the Bitcoin blockchain that was created on August 1st 2017 in order to save and preserve Bitcoin before becoming tainted by SegWit. Bitcoin Cash aims to solve Bitcoin's scaling problems, follow Satoshi's original vision, and allow users to once again transact with low fees.
Reliable, frictionless money like Bitcoin Cash will change the world's economy in ways we cannot even imagine.
Bitcoin Cash Wallet Recommendations:
If you participate in this thread, you agree to tell two new friends about Bitcoin Cash. Please don't be selfish, or attempt to cheat the system. I will be checking each account to see if it is spam.
The ONLY way that Bitcoin Cash (or Bitcoin) has any value, is if it's USEFUL and is used by people to buy and sell things. MASS ADOPTION is the end goal of Bitcoin Cash, so let's spread the word about this technological revolution!

LET'S DO THIS

Best Ethereum Wallets

Best Ethereum Wallets
When you start using cryptocurrency the number one problem is to find a secure wallet. In this article, we will introduce the most popular Ethereum wallets.

Hardware Wallets

We start with hardware wallets. These wallets provide offline storage for cryptocurrency. This kind of Ethereum wallet is considered to be the most secure.
https://preview.redd.it/ovlczorz6mh31.jpg?width=720&format=pjpg&auto=webp&s=eba30a80ba4fd2928272f3fa8dcef39da0177a8f

  • Trezor
Originally Trezor was developed for Bitcoin. Now it supports more different cryptocurrencies including Ethereum. This ETH wallet will work in tandem with your MyEtherWallet.Trezor is famous for the features that make it very secure. It provides 2-factor authentication, advanced cryptography and the opportunity to check transaction details before you confirm.
On the other hand, there are a couple of disadvantages. Such as the cost: the Trezor wallet is pretty expensive. If you are not a regular user you probably should consider cheaper wallets. Also, it takes time to access your holdings with this wallet.Thus using Trezor as Ethereum wallet may be a little inconvenient if you are a common user.

  • Ledger Nano S
Ledger Nano S is also a hardware wallet. It connects with any computers via USB. The most important feature of this wallet is security. As well as Trezor it provides 2-factor authentication. Aside from this, this Ethereum wallet has a PIN code to secure the device itself and also you can back up your account on the recovery sheet. Ledger Nano S gives users an opportunity to check details of transactions before the confirmation.
The main disadvantage of the Ledger Nano S wallet is the price. It is cheaper than Trezor, but it is still pricey.

  • KeepKey
KeepKey is a hierarchical deterministic (HD) wallet. It is also in the group of hardware wallets. KeepKey supports a lot of cryptocurrencies.The fact that this is an HD wallet allows users to generate private keys in an unlimited quantity. Undoubtedly this adds to the security level. Moreover, with the help of this device, you review and confirm every transaction. You can also set up a PIN code and a recovery sentence to make sure your holdings are secured enough.
It is easy to start using the KeepKey wallet. You need to download a couple of applications. One is to create a wallet. And with the help of the second one, you will be able to connect to KeepKey through Chrome.
Talking about the disadvantages we should mention the price. It is one of the most expensive wallets on the market to use it as ETH wallet.

Web Wallets

The great thing about web wallets is that you can easily access them. All you need is an internet connection.

  • MyEtherWallet
Unlike the most part of hardware wallets, MyEtherWallet is free. Nonetheless, it provides a high level of security by allowing users to store their keys on their own computers. There is no necessity to give any private information when creating a wallet.This Ethereum wallet interrogates with some hardware wallets such as Ledger Nano S and Trezor. Also, this platform gives an opportunity to write smart contracts.
In addition, MyEtherWallet provides automatic back up. So users should not remember about this by themselves.Moreover, it’s possible to get a paper Ethereum wallet by going to the “Wallet Info” section.

  • Coinbase
First of all, Coinbase is an exchange platform. Usually, it is not recommended to store cryptocurrency on the stock platforms. But Coinbase is often considered to be an exception. This platform has a wallet that is suitable for use as ETH wallet. It is easy to use and has an intuitive interface.
One of the major drawbacks of this wallet is that users don’t control their private keys.

  • MetaMask
MetaMask is not just a popular Ethereum wallet. It is a browser extension. It can be installed on a number of browsers such as Chrome, Firefox, and Opera. This form allows accessing your holdings easily.The good thing is that you don’t need to provide personal information for the registration. Also, there is an opportunity to store the private key on your computer.

Desktop Wallets

There are wallets that are made in the form of a software program. They can be installed on your device. Such wallets are called Desktop Wallets.The security level of these wallets is not as good as of hardware ones.

  • Exodus
Exodus is a multicurrency wallet. So it can become your ETH wallet.It is famous for its user-friendly interface. It is a good wallet for those who only start their journey into the cryptocurrency world. Exodus supports ERC20 tokens.Users store their private keys on their computers. This increases the security level. Exodus has a backup feature.
The drawbacks of Exodus are that there is no possibility to add any custom tokens and a small list of ERC20 tokens.
  • Atomic Wallet
Atomic Wallet has a very convenient interface which is suitable even for the beginners. It supports Ethereum and all the ERC20 tokens.The wallet supports atomic swaps. So you can not only have one wallet for Ethereum and all the ERC20 tokens but also exchange them with another user.
Unfortunately, it doesn’t have a hardware wallet yet. So the level of security may not be very high.
https://preview.redd.it/a810i9277mh31.png?width=1024&format=png&auto=webp&s=6b57cce28966819ea9922675e0c64180996eb9da

  • Mist
Mist is the official Ethereum wallet. So it is a full node wallet. Full node wallet downloads the whole Ethereum blockchain on users’ computers. In other words, it downloads all the data about the ETH network. This type of wallet makes any user a full-fledged member of the blockchain
Mist has developed the way to allow users to interact with their ETH storage easily. It is free. Users don’t provide private information during the process of registration. The only way to access your wallet is to use a password. Your private keys are stored on your computer.The Mist wallet supports smart contracts.

Mobile Wallets

Sometimes it is more convenient to use a mobile wallet, which can be installed on your mobile devices. This type of wallets provides quicker access to your storage wherever you are. Mobile wallets are easier to use than desktop ones, but it is riskier.

  • Jaxx Liberty
Jaxx is free. It supports a lot of cryptocurrencies including ETH. It can work on different platforms such as Linux, Windows, and OSX. There is also an extension for Chrome browser. The interface of Jaxx wallet is simple and good to use.
However, the security of this wallet raises some questions.
  • Coinomi
Coinomi is an Android app. It is easy to use and supports a wide range of cryptocurrencies. With this wallet, you don’t have to think about backup. Coinomi has a feature that helps you to keep all the information. It is secure enough. Your private keys are nowhere but on your device. Coinomi protects the user’s identity when they sign up.
Unfortunately, so far there is only an app for Android.
https://preview.redd.it/75o14iff7mh31.png?width=1604&format=png&auto=webp&s=280cdfaf6ea98e90f626e7bd9e2c3edbf2fd6ba2

Paper Wallets

Paper wallets allow printing private keys on paper. And this printed document is used as a wallet. These wallets are not that easy to access. Although the level of security is relatively high.

  • ethaddress
In case you are looking for a way to store your ETH in the most secure Ethereum wallet, but you are not ready to pay for a hardware one, try ethaddress. This wallet is free. It provides a high level of security.

  • WalletGenerator.net
The core of this key-generating wallet is 99% identical to the well-considered bitaddress.org.First of all, it’s necessary to download this website from Github, unpack and open the index.html file directly from your computer. The code version control allows to significantly simplify the mutual verification of the executable code. For more security, disconnect from the Internet at the time of creating your wallet.

How to keep your wallet in security?

Whatever wallet you choose you want it to be as secure as possible. Here are some ideas on how to achieve this:
  • Choose a wallet that suits your requirementsAll wallets are aimed at different goals and ways to use. Some of these wallets offer high security, some provide you with easy access for fast trading. Therefore, you should choose exactly what suits your needs best.
  • Keep your private key safeAlways make sure that your private key is secure and is stored in a safe place. Moreover, do not share your private keys. No, not with friends. Not even with your parents.
  • Set up 2-factor authenticationSome wallets offer this feature to increase the security of your coins. Do not ignore 2-factor authentication, set it up for extra confidence in protection against theft.
  • Backup, backup, and backupNothing protects you better from unforeseen accidents than a good old backup. This way you can keep access to your coins.
  • Store your funds offlineWith all the security levels offline wallets are still the most secure ones. Therefore, it is better to keep large amounts of ETH coins only on offline wallets.

An Idiots (me) Guide To Installing A Citizen Node.

An Idiots (me) Guide To Installing A Citizen Node.
So I dusted off an old laptop and have compiled a how-to install the Iconloop Engine and Iconservice on Linux and OSX. The directions on github are very good but there are a few issues with OSX and Xcode. Here is my simple how to with work arounds for Xcode on OSX and simple compiling for OSX. I will edit this as need be and it isn't exhaustive but rather a good solid how-to for anyone that wants to play around with our favorite open source project. Some of the packages for Ubuntu took a little searching and I hope this saves somebody some time.
Have a great day.
