I mean some alts are just pure trash and are only still alive because of whales pumping and dumping them but many are actually useful or could be useful in the coming years. I would expect to see alts rise before Bitcoin hits a new ATH in 2020 but that's just my opinion.
Alts with good potential have dumped a lot less than shitcoins, and that makes me happy.
That was becuase the project is funded by investors . there are too many good altcoins but more eth contract is not belong to them because they are totally shit.
