That is a bit of an exaggerrated percentage don't you think? Sure, a lot of the ICOs that are coming out now are scammers just trying to make some quick money from unsuspecting investors but that does not mean that it is up to 80 percent that are scams. 60 percent is more like it and people should not be scared to invest in ICOs, just be careful and make sure you are investing in a good one is all.
