From my point of view, regulation can help the crypto-currency world to start a completely new frontier in its development, but the only other thing is that crypto-currencies today have very great opportunities in anonymity, but this problem will soon be resolved.
Crypto is not as anonymous as you think, you can be tracked down if you are involved in any criminal activity.
So, don't see Crypto as a place of hide if you are a wanted person

with all your respect mate, how is that possible that a bad person can be track down? Can you give a details of how to catch them?
Through the exchange where the fund is being transfer especially if the exchange was a centralize platform? what if the platform
exchange is decentralized are they gonna tract them still?
