Dont invest in a coin that has no product cause they are only a pump and dump coins.
Buy ,dent, eth, xrb, and bitcoin these are the only coins that can give you high profit returns.
Those are not the only coins... there are many opportunities out there, if you pay attention you can see that like every day theres like new coin which gain over 50%+ in value. You may know only these coins and maybe you have researched those, but I can tell you these are not the only ones in the play.
XRB is not bad, but yet it is a new technology. I haven't really looked at how it works and all, all I can tell is because of binance potentialy was looking to add it price went up. Although idea to send fast transaction with no fees is very interesting one, not sure how are they private either because as a little reaserch I have done your amount of coins is still publicly available.
