with the way scam projects are running away with people's money, I think regulation would somehow minimize scam projects. Although I think regulation would be against the decentralized nature of cryptocurrencies. But I would prefer having a regulating body than to lose my money.
The regulation certainly aims well because it regulates crypto currency so that it is not misused by criminals or has an adverse effect on society, for example ICO as fraud.
But if it aims to hinder or treat crypto like banking, of course there are many who disagree because it will eliminate the anonymous characteristic of cryptocurrency, even though it is not anonymous 100% because KYC is still needed when withdrawing money from the crypto exchange.
