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
