Regulation is somewhat needed by crypto's right now since there are so many scam coins existing since anyone could able to create a token out of erc20 contract and government should hold that one since those are critical areas which could lead us to be more safer if government will enter the ICO's scene. I also believe that bigger markets could create a big noise so no wonder the more growth will came the more people and government pursue to get on the crypto space.
Indeed, some kind of regulation is mandatory in order to block the appearance of so many scam ICOs.
This will raise crypto's good reputation and credibility, factors of paramount importance for crypto to be widely accepted.
