indeed the XRP is currently declining, but for myself, I still hold the XRP that I have because I still believe XRP can still develop again.
I wish you luck holding XRP. It's your decision if you're going to keep on holding that coin. It is centralized and is very possible for such manipulations. Before I would like to buy it but with further research and reading people's point of view about this coin, it stopped me for buying and desiring this coin. There are also some other altcoins that are very possible to be manipulated and that's why before investing, look if there's something wrong with that coin.
