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…
Bernie Madoff lost tens of billions of dollars of investors’ money [1] in a clear fraud. This is terrible, but nobody ended up destitute [2]. The systemic risk was contained.
Contrast that with the savings and loan crisis [3]. This lost retail investors’ money. People ended up destitute. That, and lots of retail investors (i.e. non-accredited investors) doing zero diligence allowing the problem to metastasise, turned a prosecution problem into a political problem. When masses are turned on the street, nobody cares that they should have done their diligence. They become a political problem.
The government's rationale for regulating retail investors more strictly than accredited investors is that a laissez-faire attitude towards the former's activity has, historically, resulted in massive fraud that then creates political problems. I believe there is a middle ground between our total-ban regulations and Bitcoin's laissez faire. Finding that, however, will require both sides understand why we have the regulations we do.
