In the past the way it worked was as follows.

Bitcoin pumps, then it seems to stall while altcoins seem to pump and then eventually they both top out.

What happens is the whales pump bitcoin first and while people are piling into bitcoin they get out and move into altcoins and then they pump the altcoins. So later altcoins rally and typically the whales move into stablecoins and then the market peaks.

This might repeat but there is no gaurantee.
