This sounds like bad news but I see it as good news. The only way the SEC can go after fraudsters is to have jurisdiction over what they have done. The SEC can now go after the frauds against Ethereum users no matter where the fraud was committed.
Crypto will never be a legitimate investment class if people can't trust that they will get their investment back. It's also impossible for it grow to fill a need without trust. Crypto-Land should be jumping with joy at hearing this news.
