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.
This is indeed a big problem for ico where because there are so many scam projects that make people become distrustful of cryptocurrency back at this time
Patience and investor confidence ends. Fraudulent projects grow like mushrooms and become widespread. For ico, it is a disease that needs to be addressed. If nothing is done with this, it will adversely affect the cryptocurrency as a whole.
