As much as I prefer monero to btc there is no such thing as tainted btc. People will still give you the same amount of money for it. If there was really tainted bitcoin you could just send some to those whale wallets with 1k+ bitcoin and now all those bitcoin are tainted? Give me a break lol
They will not. Coins that were stolen from KuCoin ( I dont even know if there was and BTC) are all tainted and all big exchanges will lock them. USA dont trade with Iran. If they will find out someone traded with Iran they will mark those Bitcoins as tainted. Just them USA. EU and Iran will keep them as totally fine. On the other hand Iran can mark some Bitcoins that are connected with USA terrorist regime as tainted. And they will not let anyone use those coins in Iran. Since USA market is bigger than Iranian, the coins tainted by USA government will be worth less then the ones Iran tainted. So there will not be Bitcoins worth $10000 and Bitcoins worth zero, but there will be a shades between those two numbers. 1 Bitcoin will be worth 1-$20k
