2 and a please.

I'll pay when its 50% full.

This is unfortunately very difficult to achieve. Addresses do have checksums to check for errors with the mis-spelling of the letters.

It's not possible for wallets to be able to check whether the intention is to send to a USDT address or a Bitcoin address. USDT runs on top of Bitcoin which means that unless they shift away from using a second layer network that utilises specifically on Bitcoin, it's not possible for them to change the address format.

It's fairly common for this to happen and unfortunately there's no viable solution. It's not possible for the wallet client to identify which coin you're intending to send because both would be sending to the same address.

They're very common on the forum. Just report them and they'll be removed pretty quickly.

Are you sure? I've tried TrustedCoin with Electrum once and if I remember correctly,  there's a setup page which says that a small fee will be charged for each transaction,  or something along those lines. I'm not on my computer right now or I'll verify this.

Might have changed with Electrum 4.0.2.

Indeed. I remember Kano being an opponent of SPV mining and some drama between him and F2Pool. BIP152 would've improved the propagation timing further and the effects of SPV mining would've diminished from the past.

I can't comment too much on how Kano and Antpool handles their mining code nor the efficacy of their code because I can't have access to either. He does have sound arguments against SPV mining and miners are mining less empty blocks in the years after that incident.

Blockchair has database dumps here but you need to parse it to have anything useful :https://blockchair.com/dumps

I just remembered,  LoyceV has everything: https://bitcointalk.org/index.php?topic=5246271.0

The mempool has been spiking periodically today. If the trend persists, you should have the transaction confirmed within a day or two.

A little advice, don't use Blockchain.info wallet. They are pretty unreliable in terms of fee estimates and is generally a bad wallet to use. Legacy addresses results in you paying a higher total fee as compared to a bech32 wallet. Try looking for alternatives like Bitcoin Core or Electrum.

Damn, it's a pretty neat workaround. Thanks!
Yep, hope it gets introduced soon.

Locking the thread now.

Yep. I'm trying to find PMs sent by a specific person though. It works fine if I know the keywords of the PM and it's able to filter out the senders for me. However, I still can't get it to display all of the PMs sent by a specific user.

I know this is a weird content to be posting since I've been using the forum for so long.. 

Is there a way to search for PM's specifically from a user? I've tried leaving the Search For: field blank but it wouldn't search at all. Putting an asterisk in the field wouldn't work either. I've been scouring the PMs manually in the past but it's pretty time consuming.

Choose BIP141 at the derivation path part, choose P2WPKH.

I'm assuming your wallet isn't using BIP84 since it's generating both? If it doesn't work out for you, try BIP84.

Google Auth is quite a pain in the ass to retrieve if something happens to your phone but it's a decent way to ensure security.

It's always a good idea to make a backup. When you set up your 2FA, the website/program will usually ask you to copy down a string of alphanumeric letters as a backup. You can easily import that if you need.

If you don't mind sacrificing a little security, try Authy. I'm not sure how their security fare against other services but you can recover your 2FA keys using your phone number. This is kind of risky though; SIM Jacking is quite common and you'll have to take care to use a more secure email to prevent them from resetting your Authy account. But even with that, the backups are secured with a password still.

Yes. You can enter the master private key at: https://iancoleman.io/bip39/.

Scroll to BIP32 root key and paste your xpriv there. After that, scroll a bit further to change your derivation path to suit your needs.

The way Bitcoin works makes it very hard for individuals to receive clean coins which hasn't been mixed with a "tainted" coin. Every Bitcoin that you receive is likely to have been linked to a illicit activity in its history, just like fiat. Innocent until proven guilty, law enforcement cannot arrest you solely based on the fact that you're in possession of tainted coins because it doesn't mean that you're involved in the activity.

OTC trades. Localbitcoins and bisq allows you to do peer-to-peer trades. Some exchange don't accept tainted coins but as long as you're not involved in any illicit activities, you're fine.

It's specific to your local regulations and the rules differs for different jurisdiction.

Basically, for some places, they have pretty strict laws about money transmitter and those exchanging fiat to crypto (or vice versa). Some states have a certain threshold for users to register themselves as a money transmitter and for them to identify any suspicious activities to combat money laundering and terrorist financing. The transaction volume needed differs from each jurisdiction so refer to your local laws.

Bitcoin exchanges are usually registered money transmitter who have a license to conduct their business activities. They are legally obliged to flag out and report any suspicious activities, as well as having a KYC system.

Hardware wallets works by only protecting your private keys. It doesn't protect against phishing attacks by misleading you to send to a different address. It's possible for a malware to be included with the fake Electrum software to change the Bitcoin addresses that you see on webpages and key in.

If the fake Electrum software only changes the addresses that your transaction is being sent to, the hardware wallet displays the transaction details and you should be able to see for yourself and decide if it's correct. If you don't sign the wrong transaction, you won't lose the funds.

There's a simpler example of this quite some time ago[1]. The example has SHA256d of the genesis block hash as the solution for the unlocking script. It's a much more simplified and obvious puzzle as compared to OP's as it only involves one SHA256d hash.

Could've been me. I went to try to broadcast the transaction everywhere and found that Blockcypher doesn't follow the RBF fee increment rule (or didn't see your old transaction). You could've lucked out and Blockcypher relayed it to a miner who also doesn't care about the amount of fee increment.

I would say that it's an outlier and you would usually have to increase the fee enough to meet the requirement.

It's the first 4 bytes of double hash of the ECDSA private key with the appropriate prefix. It's not hard but it can be confusing for anyone who isn't familiar with the whole concept of hashing and stuff.

A leopard does not change its spot. If you're here for quick bucks, chances are, you're not going to care about the quality that you post. Afterall, whats the point of improving your post quality when you're getting the same amount of money for a lower quality? It'll take more time for them to post on all their alts too .
You need to understand; no one is forcing you to post anything on the forum. If you cannot contribute to the discussion, don't post. Go around and study on the forum, the quality of the post would be higher if this is the mindset.

It is relevant if you have sufficient resources. Bitcoin mining, right now is only worthwhile if you can do it on a large scale. The rising difficulty means that the ratio of returns to your hardware is pretty small. It's not worthwhile unless you have a lot of space and have near free electricity.

If you do have near free electricity, you can squeeze some profits out of secondhand hardware which is still good and double up as a space heater.
