Its definitely possible for waves to go up in the future and give a x3-x6 roi. I dont understand why peopoe expect too much at the start. Just give to waves time to grow and hold your coins.
I could say nearly all of the investors care about the profits. So they are fear to see the price drop and excited to see price up.
I think many speculators were blinded by ICO hype and put too much BTC in, thinking 2x ROI is guaranteed. And now they have their BTC binded in, so They cant make more money on market by speculating and trading, they are just looking for exit now, because the have no BTC for riding ICOs and markets.
