i too think the luke stash splits that end up on bc1q addresses(precise amounts of 1-5btc) will end up on those types of CEX and converted to some other currency
converting it to true fiat via those sites wont be non-kyc because doing fiat withdrawals reveals bank account holder name. so those sites will be just conversion bridges to altcoins/stable coins and them moved again before the entity doing it thinks its safe to then "cash out" or hoard back as BTC again elsewhere
I have just only one question.
Why didnt he cash the UTXO sending them pro the exchange? No one would have never known that, as those funds were not tied to him.
Now he has to be extremely careful handling those utxo's.
whomever the entity is (luke/hacker) they are not stupid to just throw coins into an exchange to cash out, straight from the "event". as the lack of taint jumps are to close to the publicly known address, which has been called out as stolen funds
their game is to taint jump and tx format change to hope they can skip passed the limits and tolerances of coin analysis where the fresh addresses of small amount wont raise any red flags when eventually entering an exchange/service
im surprised that these coins have not moved on much. i would have expected those precise(no decimal) coins on bc1q addresses to have been 'spent' through a mixer by now. several times. or looped through a non kyc exchange to swap for altcoin/stablecoin.
edit
i just checked address in tx above. and it has now split the 1btc into smaller amounts of 0.002
as have some other bc1q adddreses(taint back to 1yar) of precise amounts now split into 0.001 amounts

https://www.blockchain.com/explorer/addresses/btc/bc1qm2qljj3a64ueqfq885ne2yy9pddnez7vz4y2v5i would say beyond this point it is now hard to tell if these funds when spent are the entity(luke/hacker) or some idiot that is in receipt from some mixed funds.
but knowing (due to FATF regs) that regulated exchanges do not tolerate funds that went through a mixer, it should be fun to see what exchanges accept or reject deposits from those spends, even if the user is not entity(hacker/luke)
as for the funds the entity does get (different mixer deposit stash) they too may have issues trying to deposit into exchanges unless another taint jump ordeal is done to outpace chain analysis tolerances
