Sell ​​a part to get your initial stake back and leave the rest alone, at least if the xrp crashes you won't have lost anything.

I have 283 XRP coins, I bought them at a good price and I am in profit, if I sell, I get a net profit of €250, but what happens to me is what happens to you and what if it explodes and goes to €50 per coin? I don't know what to do.
