To clarify, this has nothing to do with the security of transactions for crypto, which are quite a bit more secure than a bank draft. This has to do with crypto that was delegated to an exchange by the owner, voluntarily, and that exchange handing it over to the government.

This law is like letting your bank give your savings to the government if you don't use it in three years, ie not so much a problem of currency as a problem of grotesquely blatant corruption.
