Exchanges don't want to risk working with Ripple. Nobody knows how this story might end.
It seems to me that if the situation were really bad, then the coin would be worth nothing. Now ripple cost still something, so there is a chance that Ripple will live
Yes, and I think that is a very natural thing, because every exchange always keeps their good name to the public and they also don't want to get into new trouble as a result of that, so some exchanges are releasing themselves with XRP tokens in the form of suspensions and deletions.
