is there a coin which rose in value just after ico?
in my memory the price always dropped first
Sure, plenty rose after an ICO hit the exchange.
XBC comes to mind (it went insane, like 30x value in weeks). XCR even rose 2-3x after the ICO.
And of course some drop. There are some in-betweeners, coins that rose after the ICO was over, but didn't hit an exchange yet (so off exchange trades)... then fell back to ICO levels once on an exchange. Not sure if that counts as a real drop or not.
Basically saying, it can go anywhere: up, down or sideways.
