I think crimes involving cryptocurrency will continue to grow in the future, just imagine that 1% of the global population use cryptocurrency and as of the moment crimes involving cost billions of dollars already how much more if half of the global population already involved.
I agree.
especially if the cashless society would become a reality in the future, the crimes involving wiht cryptocurrency will just grow even more in a rapid way since cryptocurrecny will be the one we are all going to use, criminals will don't have any other choice to supply their illegal activities but to use cryptocurrency.
To deter these crimes users and the government should cooperate for countermeasures.
They can't, imagine we are all using cryptocurrencies as fiat, and most of us are using it on illegal activities, it would be a hassle to the Government solving all that rather than solving a more worthy problem of a certain country, also countermeasures won't make any change unless they are going to take back fiat for a second option of payment method, so that we will not focus only on one currency.
