I don't think regulation can stop it at this point.
Don't you love crypto haters on facebook? They know nothing about it but can't wait to express their opinions about it's a bubble and will burst. The only reason some one would want another person's investment to fail is they are jealous they didn't profit. Imagine how much hate you would get for telling someone you hope their pension plan collapses? But it's okay to wish financial ruin on crypto investors.
This is the point I fear... most people (even quite smart ones) don't have a clue about crypto. People tend to destroy what they fear. Look around you. Even here people try to talk about equality and fairness and THEREFORE regulations. If there are no working markets inside the crypto scene, then it could still be destroyed quite easily (imho).
I love the comparison cryptoinvestment vs. pension plan. Thx for this idea.
