The decision to add xrp was made before all these stuff happens and it was a popular altcoin so it will be a good addition to let users gamble with it. If you hold alot of xrp then look at the bright side, the price was down close to 50% in 7 days so this will be an opportunity for all those xrp holders to gamble their xrp stash hoping to get something back from it.
If XRP got delisted from all exchanges because of this lawsuit by SEC then all investment from all people will burned and turned dust. Jumping atm with buy XRP with huge money would be very risky to do. Buying XRP and then let it stake to earn daily dividen would be a very long time to get BEP as well.
