I'm not convinced about altseason, especially now that Bitcoin is pumping and just breached the $80,000 level recently.
The first thing I always check is the Bitcoin Dominance every time I want to check about "altcoin season" so for me, I do not agree at all that we will see any altcoin season in the near future, I'm still expecting Bitcoin will pump more and these altcoins will experience more bloody times.
I agree with you that there will no longer be altcoin season like before, where almost all altcoins pump at the same time. But I do not agree with the prediction that Bitcoin dominance will rise to 73% and that all altcoin will completely lose their chance to grow.
Whether you admit it or not, Bitcoin will not be the only asset to grow and generate profit in the market. It is not a coincidence that ETH, SOL, and XRP have received ETF approvals, while many other altcoin may soon follow. Or Clarity Act will also be passed soon, paving the way for the development of the altcoin market.
Altcoin season has not disappeared completely. It is simply evolving and adapting to the maturation of the market. And Bitcoin's dominance will continue to decline over time.
