The problem is that most of you weren't paying attention and may thought altcoins would pump much later than BTC, but they actually did pump as bitcoin was pumping
XRP pumped by over 10x
Solana pumped by over 20x
HyperLiquid pumped by over 20x
Zcash pumped by over 30x
and so many more. So altcoins are not done, you are looking at them at the wrong time and in the wrong direction.
It depends on the time frame you use to analyze altcoin growth. For example, over the past year, neither Hype nor Solana showed the kind of growth you’re referring to, and if you look at altcoins as a whole, most of them have fallen.
Both now and last year, there weren’t that many altcoins that actually showed growth alongside BTC. The fact that BTC’s dominance isn’t going to decline and remains at a high level indicates that far from all altcoins have shown growth.
