the number of cases of ico scams makes investors lose confidence before investing with the ico project, but I think investors also know about this and of course they will return to invest with ico after the market has improved again.
that's true investor really lose their cofidence when it comes investing on ICO because of that causes. for me i don't believe that they will return to invest when market stabilize again because for sure they are afraid now to spend money again on it which is since market collapse also they cant obtain profits on it.
