It really is hard to believe that there are some ICOs who are intended to scam people. There are all hypocrits and rely on the weakness of people especially those who are new to bitcoin. So sad.
This year there are a lot of such SCAM companies. According to statistics, about 40% exit the market at various stages. The good news is that now included activists (whistleblowers).Your statistics is too good to be true
I've seen more terrible numbers, for example, Cointelegraph says here that it's 80% - twice more! And it was 2017... https://cointelegraph.com/news/new-study-says-80-percent-of-icos-conducted-in-2017-were-scams/ampSo the statement about "scams're everywhere" is absolutely true.
