But even on their toping in value, the dominance or say popularity of the US dollars can't be underemphasized, some of the top currency in value might not even be in serious use outside it's country of origin like US dollars. That's what happens when a new cryptocurrency is made, Bitcoin continues it's dominance, while within not more than a year the new crypto next chapter is extinction.
In many cases, yes, but currencies like Ethereum, Monero, which is nearing a new ATH now, TRON, which has also been doing pretty well lately, and some others don't disappear after a year or two. They
can crash, of course, but it's very unlikely since they've been around for years. But Bitcoin beats them in that respect, and that's why the likelihood of it crashing is even lower.
