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.
I think the anonymity part when it comes to cryptocurrencies is actually why regulations is needed. If the crypt ocurency projects are transparent, vividly transparent when it come to the team and devolpers, I think the kind of fraud recorded won't be so high.
