This is why "crypto is a money laundering machine!" narrative is not true. Binance has been freeze funds sent by Cryptopia hackers, it is very easy to tag suspicious transaction on the public blockchain network.
to launder money you don't use a currency, you use a business that you can put your money in and mix it with clean money that is coming from the revenue of that real business and get the bigger outcome of the mixed money out and also pay the taxes on it to thro off the investigators and have clean money.
using cryptocurrency does none of that and that is why it is a foolish thing to call it "money laundering machine".
