Criminal organizations must be seeking same optimal risk/fee balance as any other. Cons of cash is, it is hard to move around. Some may use cash only, some a proportion of both, what makes you so sure? You can imagine two bitcoin wallets cash/date-gapped in some low-control country for a meaningful fee and now you have at least a grey wallet instead of black one. Do you think that FBI agents sit at every crypto exchange and watch who does what? Or is there something that prevents from incrementally laundering the money this way?
