Bitcoin is pumping so alts *would* be pumping too, except people are worried about most of them being securities, becauseof Gary and the SEC right now. Bitcoin forks generally aren't securities.

But it's not really pumping ATM, unless you mean it's a usual rotation. As in Bitcoin pumps and then forks and then alts.
I mean bch IS having an abnormal run, last week it was at 200 (which is already wayyyy too high), now its 320ish. My only guess is that it's absorbing some money from the type of people that hate the idea of not being "diversified," and can't buy Solana and Polygon anymore because of Gary. Alts pump harder and crash harder.
