The news from the SEC should actually be seen as good news, for the most part.
The space was starting to spill over with clear as day scams and it's very plausible that what they learned from the ongoing cases prompted them to finally act.
It was almost a certainty regulations were coming when large corporations and entities got into the crypto space. Remember, some of these folks have enough money to found them, break them up, bankrupt them or send lobbyists to Washington to change policies.
Now here's where things start to tread into the unknown and I don't mean for this to be seen as FUD, it's just some thoughts.
Will getting listed on foreign exchanges be an issue for US based ICO's or will it just be business as usual?
There might be more of a clear separation now in terms of what we find in wallets and exchanges and the few ICO's that messed up and allowed foreigners to invest, only to refund them later will probably do a better job of making sure that doesn't happen or at least as often.
No.2 could be seen as a positive and negative but it'll take some time to see how that'll play out.
All the other news, is really nothing to panic or lose sleep over.
