I think that SEC intervention in ICOs will be good for QUALITY ICOs. It helps clean up the image of what an "ICO" is. I've spoken with many influential people in the space, and they all agree that ICOs have a bad reputation right now.
Broader regulations will force innovation within the privacy space IMO. As governments try to exercise more and more control over cryptocurrencies, people will flock to privacy coins like XMR, ZEC, PIVX, NAV, DASH, ZEN, and we'll see innovations in decentralized exchanges. I'm expecting 0x to surge in value, long-term.
Thanks for this awesome post!
