BTC hasn't even topped, I reckon it hits 150, but that'll happen in October/November, and this means that if alts will pump then the pump of alts will probably be sharp and quick and happens October/November.
This is textbook how it has happened for over 12 years, except in 2017 when the pump mostly happened in December
Right, I expect another bigger pump is on the horizon for BTC before the top sets in, alts will probably pump in a parabolic way for a relatively short amount of time as you've pointed out. That's the moment that everyone seemed to be timing in taking profits lol.
I think it will probably not be that different this time around, maybe a little bit early or later.
