2.66 BTC fee for one transaction

[BTCtester.com]

Who decides about the fee amount for a bitcoin transaction? It's the sender alone, he might have delegated this decision to his wallet or provider. E.g. in BTC transaction 3ba0c9eaf3185898164518cda7e3433d1d2049188d737f2b2a7e188aaeb8b4de someone sent 0.01088549 BTC and paid a 2.66038352 BTC fee.

The standard explanation for this is that it was a senders mistake. But it could be as well money laundering. If the sender is the miner or a person dealing with the miner it could be that this fee close to $100k was paid by intention to convert bitcoin from criminal activity into miners coins which are usually seen as innocent virgin coins.

How to investigate this? If the transaction was not in the mempool of the most nodes or if the transaction wasn't in orphaned blocks at similar time then it's very suspicious that the fee was given to the miner by intention to launder the coins.

Ait could be that this fee close to $100k was paid by intention to convert bitcoin from criminal activity into miners coins which are usually seen as innocent virgin coins.

Only the coinbase reward of miners count as virgin coins, the transaction fee is obviously from an address and has been involved in multiple transactions before then.

Crime is not the only reason why someone would want to obfuscate the trail of transaction. Privacy and freedom are essential parts of Bitcoin and one can take extra effort at maintaining that.

Based on that transaction it has a large number of outputs including small BTC so I think whoever made it doesn't know how to consolidate the transaction.
He sent only 0.01088549BTC why he didn't just choose one output with that amount to send and pay the fee less than the fee from this transaction. It has 750+ outputs which is one of the reasons why he pays a large fee just to send a small amount.

I'm sure this is a newbie he doesn't know how to consolidate the transaction to get less transaction fee in the future.

I don't think that's the reason and it won't help to make your BTC clean and actually if someone mine that blocks with that transaction it's randomly distributed to the miners(from pool to miners). They can not control this to give the fee to selected miners and only pool operators can manually select what transaction they want to include on the block but by default most pools automatically choose a transaction with a large transaction fee.


Also, if you want to make your BTC clean you will need a mixer to convert your BTC(Bad) to BTC(Clean) there are lots of mixers and you don't need to pay a large fee for mixing like the mixer under my signature.

But the guy's transaction was at a fee rate of 5,187.2 sat/vByte. Sincerely even if it was a newbie, What Kind of evil wallet suggests 5,187.2 sat/vByte as the fee rate for the transaction to be confirmed in the next block?    400 or 500 sat/vbyte would be understandable even in times of high fee rates but 5K+?  Damn!

You cannot separate the coinbase rewards from the transaction fees because they are contained in the same UTXO. If you consider the TX fees to be tainted, then the block rewards are also tainted. Then, we would have no such thing as clean coins. Most do not consider transaction fees as "tainted" and are thus as good as clean or virgin coins.

5000 satoshis per vbyte isn't particularly unreasonable 8 months ago. Though they obviously could've paid lower fees. It can be intentional, or not. There is no point speculating on this.

there was something on that transcation no one crazy enough to sent 2 btc for fee

but your theory was right, but if the bad guy trying clean his money why not choose bitcoin mixer or just using decentralised exchange and bridge the transcation to other chain

is strange enough for me ?

and if he decide to make new virgin coin from ne block the reward will be split right? or the block will find by somebody else

You don't need to broadcast your transaction. You can just inform the miner cooperating with you to add it to the next block. And the code is open source. It can be changed.
