how does that work? genuinely curious. so sure, its a fake investment where you can hide money from the irs..but if actually does turn out that no one wants to 'buy' your number for 5m what have you gained?
So you have 5m in dirty money under a mattress. You buy crypto with it. Put up a 5m NFT, buy it with the "dirty" crypto, then cash out the crypto into a bank, and no one can prove you were the original owner of the crypto, so it's all clean.
