Considering the momentum gained thus far, I don't think that regulation can stop it. There might not be enough popular sentiment to unseat Congressmen who see crypto as a threat yet, but I have a fair amount of confidence that once the Millennials find their feet, hands and voice, it won't matter.
Crypto is here to stay. The only thing that matters now is the rate of adoption.
regulation can't stop it - but it can definitely slow the momentum and change the market sentiment.
