I've been following this case from the start and I really hope that Ripple doesn't settle... and I honestly don't think they will. They've spent all this time absolutely calling out the SEC on their illogical claims and nonexistent evidence. The SEC lawyers don't have much, so they've just tried to delay however possible, and the Judge is getting pretty fed up with them. I think Ripple are going to try their best to force the SEC to make a decision on whether XRP is a security or not. I don't think they'll let it go or settle until they get that.
If they don't, I think they might consider moving to another country and the US might miss out on that particular innovation.
If the SEC is forced to make a ruling that XRP is not a security, then only BTC and XRP will be clarified. ETH was given a pass in a speech by Hinman, but might not stand up.
The wild thing is... the SEC probably would have won easily if they just targeted Garlinghouse and Larsen... but they stated that XRP has always been and always will be a security and everyone who has ever held XRP ever has dealt in securities.
I don't think they will either. Every single thing they say points to the fact that they will go for the throat and they are all in to the end. Kind of awesome when you think about it.
