I'm curious where you got that information from. It's not that I don't necessarily disagree with you but am curious as to what makes you think that.
Regarding your point about the alts, I think things may develop a little differently. Alts rely on BTC. Once (IF) BTC falls then so will the alts. I don't see them falling without BTC though. 'It would take defeating the pride leader in order to kill off the entire pride.'
Well if you want to compare the dotcom bubble peak with the current "crypto bubble", the dotcom bubble peaked at several orders of magnitude higher than the current amount of billions invested on the cryptosphere. Jeff Bezos is worth more than Bitcoin's marketcap I mean c'mon. And this is a global market that never sleeps, we have never seen anything like this. It would be a mistake to sell now because of the $10,000 psychological barrier. We are going much, much higher during the next decade. The sky is the limit and most people will too early. Maybe we never see a peak during our lifetimes.
In any case notice how Amazon went higher than it was during the dotcom peak bubble, it's all about holding the Amazon of crypto and that's obviously Bitcoin.
