Because XRP is an pumped bubble with no use cases. They were promising to be a link between cryptocurrency and financial institutions but made very little to really become one. People are pumping XRP because it's cheap and it's an old coin, accepted on most exchanges. But is anyone using it to really transact? People are only looking for a go to coin when Bitcoin is plummeting and that coin used to be ETH but this year ETH is not doing so good fundamentally so there's always cheap XRP.
I'm ready to bet that Bitcoin will not experience a 90% correction this time.
Any coin can potentially go through that significant of a correction, and while it may not be likely that it happens to Bitcoin as well, the possibility is still there. What's Bitcoin being used for? What prevents it from correcting 90%?
Bitcoin last year peaked at $19,500 from where a 90% correction would mean a bottom of $1950. Is it really that unlikely? Back in 2017 the price dipped slightly below the $800 mark and pumped straight to $19,500.
I'm not saying it's going to happen, I don't even expect it to happen, but I'm not discarding it either. We have to remain realistic here, there isn't much other than speculation to hold on to. Use is negligible at this point in time.
