How to avoid?
Simple just believe to yourself, if you feel you will get scammed so don't invest, that's it

I think that it's better to stop investing in ICOs. ICOs market is dead now.
Stop? hmm in my point of view some of us will can't to do that because investing at ICO project looks like a necessity. they aware if they get scammed but they still invest on other ICO project. i know it's weird.
. . . .Of course, there are good ones, like bittorent which has alredy made x5 profit from ICO price. But it was supported by Tron team.
I think if without tron, the possibility of BitTorrent will also be quickly dead.
