I do get your point and i quite agree with what you said here. Mostly all or some of the altcoin may pump sometimes, however putting much hope that they will reach new ATH is definitely not too good since the chance's is very slim.There has been a correction in the market and as such not all crypto will bounce back .
Bitcoin had proven it's worth over the years and as a result there is high adoption rate, so the possibilities of hitting new ATH is there. Aside bitcoin no other crypto will reach new ATH after they have dump.
