Do you mean xrp / ripple ? If yes maybe because ripple already implemented to real finanvial banking system they proof they already worked with american express. Yes ripple is centralised blockchain but maybe that news which makes people fomoed and also i read somewhere south korean bank will implemented it as well.
I guess he meant IOTA, Cardano, EOS, Stellar, etc. For exmaple, IOTA gained x14 in just one month without any new viable product or so on.
Those are 100% speculation pumps and I'm staying out.
