[Question] I use Bitcoin Core. Is it poor practice to create a new receiving address to receive all unspent funds from another address (in the same wallet) that is associated with a transaction?

I understand that if a bitcoin address is used to send funds, then its public key is disclosed and it is best practice to zero it out. Short of creating a new wallet, I am thinking about creating a new receiving address in the same bitcoin core wallet and send the unspent bitcoin to the new address.
Is this good practice, or am I doing something really silly?
From a privacy perspective, I get that idealy you want an address to receive exactly once, and send exactly once to minimize the ability of analysis to connect the dots between 'businesses' and 'customers'.
From a security perspective, I believe, an address' public key is only exposed when it is used to send. It can receive limitlessly and its public key is not exposed.

This all too common story of bitcoin loss shows why all wallet software should default to returning all unspent funds ("change") to the original address that presumably the owner has the private keys all backed up for.

Why is it said to not be safe to reuse a public key? Say I keep sending BTC from the exchange to a paper wallet where it'll all just accumulate and sit unspent for years until I sweep it to cash out, what's the harm in that? /r/Bitcoin

Ledger Live adds Coin control: Here's why that matters.

Ledger Live adds Coin control: Here's why that matters.
Ledger Live version 2.11.1 (download link) adds Coin control for power users.
The coin control feature gives advanced users more granular control over their wallets. It enables them to change how and which coins are selected when making transactions. This increases their ability to manage their privacy and the network fees they will have to pay to spend their account balance.
More control over your coins

How does it work?

The account balance for Bitcoin and its derivatives consists of all the unspent transaction outputs (UTXOs) in the account. You can think of UTXOs as the coins in a regular wallet. When you receive money, you collect coins in your wallet. Then, when you want to make a payment, you get to choose which coins you pick from your wallet. Do you pick the largest coins first? Or do you want to spend all the smaller value coins to lighten up your wallet? Similar considerations can be made when creating a Bitcoin or Bitcoin derivative (altcoin) transaction.
Before the Coin Control feature was released, all transactions involving Bitcoin (and altcoins) automatically selected their coins using the First-In-First-Out (FIFO) algorithm. This strategy includes the oldest coin in the account, and when the amount is not sufficient the second-oldest coin is added, and so forth.
As of Ledger Live version 2.11.1, users are able to make use of a dedicated Coin Control tool to choose the coin selection strategy and the coins that may be spent.

Using Coin control in Ledger Live

Coin control is available in Advanced options in the Send flow
  1. Click on Send, choose an account to debit, and enter a recipient address. Click on Continue.
  2. Enter an amount and click on Advanced options. You will then see: - The currently selected, default coin selection strategy: Oldest coins first (FIFO). - A toggle to enable Replace-By-Fee (RBF). - A toggle to include coins from unconfirmed, replaceable transactions.
  3. Click on Coin control. The coin control modal opens.
  4. Select a Coin selection strategy from the dropdown menu: - Oldest coins first (FIFO). This is the default strategy that spends the oldest coins first. - Minimize fees (optimize size). This strategy tries to minimize the byte size of the transaction by spending the lowest number of UTXOs. This results in a low network fee. - Minimize future fees (merge coins), This strategy includes the maximum number of inputs so that a potential future price rise does not make smaller UTXOs economically unspendable. If the price of a crypto asset increases too much, small UTXOs may become worth less than the cost of the network fees to spend them.
  5. Select which coins may not be included in the selection by unticking their checkbox. The SELECTED indicator shows which coins will be included in the transaction. By changing the selection strategy and/or coins to include, the user has precise control over which coins end up being spent. The Coins to spend and Change to return indicators show how much is spent from and returned to the account.
  6. Click on Done to return to the Send flow to verify and send the transaction.
The coin control window lets you select the strategy as well as pick the coins. Coins marked SELECTED will be included in the transaction.

Coin status

The following statuses can be displayed for a coin:
  • Coins received in a transaction with 0 confirmations without RBF enabled: PENDING
  • Coins received in a transaction with 0 confirmations with RBF enabled: REPLACEABLE
  • Coins received in a transaction with 1337 confirmations: 1337 CONFIRMATIONS
By enabling the toggle Include coins from unconfirmed, replaceable transactions, replaceable transactions can be selected in the Coin control screen.

The Privacy use case

One of the main use cases for Coin control is to protect one’s privacy. UTXOs are, unfortunately, not perfectly fungible due to their unique history on the blockchain. Therefore, users may want to spend coins from different sources without mixing them together, because this would indicate to an outside observer of the blockchain that these addresses belong to the same account. For instance, if one were to spend coins bought on a KYC exchange, which are associated with the user’s identity, together with coins bought anonymously using cash, the anonymous coins could be linked to the user’s identity.
Another example would be that you would like to prevent spending a high-value coin for smaller purchases because this would unnecessarily show the person you’re paying how much you have. This is similar to not showing the boulanger how much is on your bank account when buying a baguette.

Let us know what you think!

We are excited to release this new feature because we think it will fulfill real needs of an important part of our users. This version of Ledger Live marks an important milestone, but we will continue working on more features that our community wants.
So, we invite you to try out Coin control in Ledger Live and let us know what you think! All feedback is welcome on this thread, on ledgerwallet, and you can send suggestions or get help through our official contact form.
We'd like to close out by underlining our commitment to the Bitcoin community, and our willingness to build the best wallet ecosystem for newbies as well as for power users.

Possibly scammed, need any technical advice please! :)

Hi bitcoin!Situation:
I am a professional poker player and ventured deep into the abyss of shady/dodgy sites. Why I did so is still a mystery to me. Long story short, I finally made two withdrawals totaling approximately $3,500 to $4,000 via BTC. Next day, I load up my Ledger and see I have my balance. Awesome!
Oh wait...it's not spendable.Surely it just hasn't confirmed yet, right? No big deal.
Then I look at the transactions...https://blockstream.info/tx/35c1ff29f22c251b67829ce6046a7441aa81dd67d1b6b3fffb3c518fa7a19b2b
andhttps://blockstream.info/tx/e65394e7a7c8fce0eeabef3709368ad032bee7a531fed6ac002823c4ad697970
Previous withdrawals were sent to me with a more normalized fee structure.These were sent with what looks like a near-zero fee.
With my limited technical understanding of BTC, this means the transaction will either get stuck for a VERY long time, or it will never confirm and eventually be returned to him.This person has blocked me on socials and has said on the discord server for the site that "the site is better off without him"
(Basically as a good professional player he didn't want me beating his small community of players)
I'm ok with this as long as I don't get scammed.
Is there anything I can do at this point?

Edit #1: Thanks a ton to u/jcoinner for the extensive help with spending the unspent coins via CPFP (child pays for parent) The transaction appears to be confirmed!
Using CPFP has successfully spent the unconfirmed coins back to a different wallet of mine.
The txid is: 6d65c98ea01bad8d98045794729b7d1b93936a11faad0e3bd126e9223d2ee297
and appears to show a confirm and my coins are spendable.
I believe this persons' intention was
"Send a transaction that's very likely to fail and if it does I'll scam and if it doesn't...oh well."

Thank you so much reddit!

Price increase drives 98% of Bitcoin holders into a state of profit.

Price increase drives 98% of Bitcoin holders into a state of profit.
by Mickael Mosse
The price of bitcoin jumped significantly on Wednesday after the payment processor Paypal announced cryptocurrency support. The jump in value has pushed a large number of bitcoin holders into a state of profit, according to Glassnode “percent of UTXOs in profit” statistics. Based on the current data, 98% of all bitcoin UTXOs are in a state of profit touching levels previously recorded three years ago in December 2017.
The price of bitcoin (BTC) closed at a high at $13,184 per coin on Wednesday, October 21 following the announcement from Paypal. During the evening trading sessions, the onchain research and analysis firm Glassnode tweeted about the number of bitcoin unspent transaction outputs (UTXOs) in profit. A UTXO refers to the amount of bitcoin someone holds that has not been spent and is simply stored in a bitcoin wallet.
“98% of all bitcoin UTXOs are currently in a state of profit,” Glassnode tweeted. “A level not seen since Dec 2017, and typical in previous BTC bull markets.”

https://preview.redd.it/1dtqk311dvu51.png?width=1450&format=png&auto=webp&s=67b10a88f9891ade45f459dcf03fc70bad23b5c9
Since then the price has dropped a hair but the price of bitcoin (BTC) is still up 4.3% over the last seven days. Long term holders have seen a 72.4% increase during the last 12 months, 34.9% during the last 90-days and 22% against the 30-day span. Glassnode’s onchain stats report, details that the subindex measuring investor “sentiment” increased ending the week “at 70 points.”
A number of crypto analysts and traders believe that bitcoin’s current price range is a key indicator for moving forward. Moreover, BTC’s dominance level, it’s market cap measured against all 7,000+ crypto assets, has risen to 63.2%. The senior financial analyst at Fxpro, Alex Kuptsikevich, believes bitcoin is testing crucial macro levels.
“At current levels, Bitcoin is testing cyclical highs,” Kuptsikevich wrote in a note to investors. “Since the beginning of 2018, it has not been able to gain a foothold at levels above $12,000. It is equally important that at new highs, indicators like the RSI are far from the overbought condition, indicating significant potential for further growth. Closing the week above $12,800 would be the highest level in two and a half years, opening a direct path of growth to the historic highs of $20,000 that we saw three years ago.”
Kuptsikevich added:
Bitcoin breaking through two round levels of $12k and $13k opens doors for further growth. The current price dynamics led the coin to re-test the peak of july 2019, which at that time was the highest point of the rally. Nowadays, purchases take place against the background of confidence that bitcoin has more and more supporters in the traditional financial world.
Eric Demuth, cofounder and CEO of Bitpanda believes that cryptocurrencies, in general, started to “establish themselves as a trusted asset class of the worldwide financial market such as gold and stocks.” Demuth thinks that the Paypal support announced on Wednesday is just the start, as he believes more large players will be joining the crypto party.
“2020 has shown that crypto is here to stay,” Demuth explained. “There has been a huge inflow of institutional capital as well as record numbers of new retail customers adopting cryptocurrencies. I am certain we will see more big players like Paypal joining the party in 2021.”

Expose private key with Shamir recovery seed

I have a friend that sent litecoin to their bitcoin address starting with 3. he got the trezor model T setup with Shamir share seed. Reading documentation is clear that Bip39 recovery tool would not work with the seed. What options do we have to help him access the private key and move the unspent LTC to proper wallet?
Your help is much appreciated.

Blockchain.com support hack attempt

TL;DR: Wrote blockchain.com support on an issue, got a fraudulent email from blockchainexchange.vip asking for my 12 word seed.
Today I was trying to send some bitcoin out of my blockchain app, and I got a notice saying I had too many unspent transactions, so the fee was going to be higher. I read that moving all funds to a new wallet will solve this, but when I attempted to do so, only half of my balance was available to be spent, which is very strange, since I have no pending transactions.
So I went to blockchain.com support site, and wrote an email asking for a solution. I got an email a couple hours later from [[email protected]](mailto:[email protected]), but when I looked closer, it was actually [[email protected]](mailto:[email protected]) . That raised some suspicions. When looking at the support ticket, it was a completely different number.
What came after is even worse. David from support goes on to write that I the wallet out of sync with their database, causing balances not to show correctly.
He goes on to instruct me to backup my wallet, and asks me to send the 12 word seed, and once I did that, my wallet would be synchronized again.
What I don't understand is how this is possible? I was on their site, looked for answers on Wallet consolidation, and clicked on submit a request.
And I still dont have an answer on why my spendable value is less than half of my wallet value

How Ethereum Works

How Ethereum Works
The structure of the ethereum blockchain is very similar to bitcoin’s, in that it is a shared record of the entire transaction history. Every node on the network stores a copy of this history.

https://preview.redd.it/ga09hr7rxz241.png?width=2550&format=png&auto=webp&s=ed5d5b299733b26548f6afe17b26caa5e7d29d95
The big difference with ethereum is that its nodes store the most recent state of each smart contract, in addition to all of the ether transactions. (This is much more complicated than described, but the text below should help you get your feet wet.)
For each ethereum application, the network needs to keep track of the ‘state’, or the current information of all of these applications, including each user’s balance, all the smart contract code and where it’s all stored.
Bitcoin uses unspent transaction outputs to track who has how much bitcoin.
While it sounds more complex, the idea is fairly simple. Every time a bitcoin transaction is made, the network ‘breaks’ the total amount as if it was paper money, issuing back bitcoins in a way that makes the data behave similarly to physical coins or change.
To make future transactions, the bitcoin network must add up all your pieces of change, which are classed as either ‘spent’ or ‘unspent’.
Ethereum, on the other hand, uses accounts.
Like bank account funds, ether tokens appear in a wallet, and can be ported (so to speak) to another account. Funds are always somewhere, yet don’t have what you might call a continued relationship.

Did I just lose 1BTC?

Freaking out right now. I purchased some online goods for 0.005 BTC on August 13 and all was well. I haven't updated my bitcoin wallet for a while now and I am on Bitcoin Core 0.13.2. I just checked the blockchain and it looks like it sent 1.005 BTC instead of 0.005? In my transaction history it shows up as 0.005 being sent in my core, but 1.005 on the blockchain. Did I fuck myself over by using this outdated wallet?

Example of a Bitcoin transaction with unspent Output. Images from Shutterstock and Amazon. Instead, the wallet will send the 1.75 BTC UTXO and the Bitcoin network will take that and mint two new UTXOs. One will be valued at 0.25 BTC and go to the Amazon receiving wallet, and the other will be valued at 1.5 BTC and will go back to your wallet as change. Maybe your wallet has a number of 0.1 BTC ... UTXO stands for Unspent Transaction (TX) Output. Every on-chain bitcoin transaction sends bitcoin to one or more addresses, from at least zero (in case of a coinbase transcation) addresses.. A bitcoin wallet balance is actually the sum of the UTXOs controlled by the wallet's private keys.. UTXO set. The UTXO set is the collection of all addresses with unspent outputs. Whenever you need to make a payment to someone else from within Bitcoin, it won't register on your wallet that you effectively made two transactions when sending money to this one individual. The reason for this is because everything happens behind the scenes. Whenever you make a new transaction, a brand new address will receive your transaction fee. This is what we will more simplistically ... A Bitcoin wallet is not the same as a physical wallet, however. It doesn’t receive or hold any money. Instead, it stores the digital signatures that allow you to sign transactions. Bitcoin ownership is assigned and maintained through the shared public ledger—the blockchain.
