I don't want to be that guy but surely if BTC continue to rises, and personally I think it will.. Won't Waves drop slightly further? 
I hope so. I know that sounds bad but anyone with btc right now can make a killing if they are buying alts at these low prices. I'm wondering how many people have either dumped at a loss or are bagholding. I'd say quite a few. Anyone just starting out buying into Waves right now is very lucky. 
I completely agree, it really is a great time to buy any cheap alts. BTC won't go up forever there will be a selloff eventually so my guess is around $1k BTC mark and then we'll see a jump with most alts, but god isn't it an amazing time to be in crypto!
