After the news on lawsuit, some FUDs on delisting were released to break the support of XRP. They succeeded but after the fear is cooled down, it looks a little better for XRP.

If XRP will actually be delisted on US-based exchanges, it will not be then end of XRP's lifespan. Many cryptocurrency were prohibited in the USA and Poloniex, Bittrex deslited them since 2018 and 2019, but they are still be traded on many other exchanges.
It is for trading, to have safe storage, choose wallet you can control your coins (people gave some in their replies).
