The scenario could be possible, however there's nothing much we can do about it but the least we can do is to secure our asset and financial info to avoid the hackers and scammers in accessing this route.
While money laundering happens everywhere not just crypto it also happens with fiat. So, I guess there's nothing much we can do about it as well but to trust it to the authorities.
Speaking of authorities, we don't have it in crypto because it is not yet widely regulated. So, again this makes the narrative "there's nothing much we can do about it" stronger lol.
