Perhaps the exchangers will become the place to do the money laundering? I mean still depends on the what kind of regulation they will impose on the exchangers. If it just tracks the transactions happening at the exchanger then it wont be much useful as our addresses still remain the anonymous. There are services like bitcoin mixers where we can get the anonymous characters unfolded and no will know we were the one who did that transaction. Correct me if I a wrong with this ? There Will always be different ways of making the whole transaction anonymous and thus keep it untraceable. This is as long as we do not transact in the bank accounts. However the later is still the same case as if today.
Yeah your correct, but the thing is most of the cryptocurrency holders still relies bank transactions to convert their fiat to crypto and vice versa. So still, transactions can be traceable, I agree with others, regulations are still needed but not to the extent of removing the anonymity of cryptocurrency.
