Altcoins have already started to explode at an average of 80% right now. Recently pumped coins ZIL and GMT are popular and the pumping seems to continue.
I don't know why but I don't consider pumped coins as viable player during bull run, as most of them just have a flash sell-off that don't last the test of time and ultimately crash down at every interval.
I know in the coming month altcoin is going to see another bull season and this time it going to last longer not just some pumped and dumb shit like we use to see with most of the meme coins.
