Serious question: Is there any use case for cryptocurrency and/or NFT’s that isn’t going to primarily result in illegal usage, scams, or grift? I completely understand the desire for a non government controlled currency; my issue is that it seems this is a nightmare of theft, money laundering, etc. that completely erases any possible positives from it. I also understand that this stuff also happens with fiat currency, but it seems to me the magnitude is on a completely different scale.
