I think that the cryptocurrency/blockchain space is the next big thing in the world on-par with the internet. But it still has a long way to go. In the late 90s you could say "X on the internet" and get tons of investment. Now it's the same but with "X on the blockchain". We are going through growing pains now, and there definitely needs to be some regulation introduced to curb the many scams. My personal hope though…
Who would enforce regulations? You would necessarily have to centralize things and hand over power to an authority. This would defeat the purpose of a dencentralized blockchain.
