Ripple really falls apart and the possibility that coin base going to delist XRP might come to reality. Other US-based exchanges might experience this as well. Unfortunately, other exchanges are also making their move, Bitstamp just announced that they will halt XRP trading from US customers. This could be a domino effect if XRP loses their lawsuit unfortunately.
As long as the delisting of XRP is not connected to exchanges that do not have American jurisdiction, the coin will be relatively safe. By banning American citizens from working with XRP, Bitstamp is seeking to avoid a potential conflict with the SEC. I expect that other exchanges will do the same.
I think that ripple will not fall apart in the end if the accused leaders are able to pay the penalties. It is quite obvious to me that the SEC will win this lawsuit, since the evidence of the alleged violations is fairly easy to collect and will be undeniable. However, in any case, the ripple's reputation has suffered serious damage.
