I agree, but right now BTC is ATHing everyday, so it's a special situation. It makes sense that people dump alts.
Hopefully, when BTC will dump and stabilize we will see green everywhere.
Well guess what's going to happen with many alts when sidechains, drivechains, atomic swaps and lightning network gets implemented in Bitcoin??
A huge amount of altcoins will probably decrease even more in value.
Altcoins will be the new type of penny stocks. That's it. When you know how to trade them you will and can make great money with it. But don't expect anything big to happen with them. 5-10 coins may have serious value, the resit will stay as pump and dump.
