I have nothing against wanting to invest in altcoins. But I do believe that only very few and close to little altcoins will reach new ATHs. Maybe they will just rise for a few times but ethereum or xrp may not reach their ATHs again. There are other reasons why one would want to invest in altcoins like transactions purposes but I believe if you are hoping to see a coin reach new ATHs this cycle, it will only be bitcoin.
Yes, it seems there is no more season for altcoins as there always used to be. If there were to be a season for altcoins by now, they should have risen to a certain price. In fact, the way altcoins were trying to pump when Bitcoins price was leading to $100k shows that all these altcoins like Ethereum, Solana, and BNB and others would not be at the same price now. So, I also think there will be no new ATHs for most altcoins. In fact, even those altcoins that reached ATHs are mainly from projects that just launched, not over a long period.
But the reason many altcoins will not reach ATHs again is that people are now wiser. Many altcoins are just a game, and if someone isnt smart enough, they will be the ones used to cash out big bags. Also, I think the main cause of these altcoins not having solid investors anymore is that it seems the same big investors and developers are behind many of these projects. So, there are no more big funds to pump and later dump the coins and the and average and small investors
in crypto industry are now wiser and prefer projects where the risks are more consider,so them are now investing bitcoin.
