I think many people after getting pumped n dumped so many times have decided to stick with the real world coins like Ethereum/XRP.
Unless coin is not used by business, merchants, and people for something more than simple speculation it is nothing special than the worst shitcoin.
Bitcoin has pretty much hit its potential maybe a 2x left in it.... But I believe it will eventually be overtaken by XRP.
How do you know that bitcoin has reached its potential? If you think that Ripple, a coin created by corporations and Banks will be better than sovereign coin like BTC, think twice.
This is for many functional reasons but also because XRP is regulated while becoming decentralized.
Bitcoin can be regulated as well, we can see adoption growing, Japan accepted BTC as legal payment method, Australia will do the same in July.
