Quite a few ICOs have fallen flat straight after listing on an exchange. The most recent ones which I myself have bought in or was watching and didn't perform as well were:
Zeepin - ICO price at $0.13, fell to just $0.08. Probably caused by whale dumps. Has recovered slightly since then.
Wepower - ICO price at $0.125, fell to $0.13, lots of dumping due to market crashes at the time of release.
Copytrack - ICO price at $1.3, currently at $0.40. Released on a low volume exchange.
Im not going to buy in to any ICOs for a while, at least until the market recovers to at least a market cap of $500b, which hopefully should be soonish
To my mind, ICOs now are the safest way to stay alive at the crushing market))) alts are going down, but when you buy in into ICO. you may be pretty sure, that after month or two you will have at least the same amount of money, and maybe x3-x5)))
