I wonder how law applies in US or EU, when you wanna sell your KYC btc bought on CEX by peer-to-peer transfer ( let's say via bisq or in person ) because you wanna avoid a bank transfer and get cash.
Let's say you sell your 0.01 you've got on Binance two years ago today with a profit around 100 %.
You have the 0.01 in cold starage at address bc1xxx. You get to send it to a bc1yyy you've got from a buyer
The buyer sends it from bc1yyy to a whirpool and gets a 23k sats in badbank that he then joins to a tx0 transaction with a previous mix badbank of 80k sats left of his 0.05 nokyc btc into 0.001 pool.
Is it enforcable to claim that it was me who mixed the funds and i will have to pay a tax from buyers 0.05 at some point ? Is it now pressumed that i own more than 0.01 ?
