The problem with ICO is that when there is not enough promotion and the project didn't reach the soft cap, usually they tend to slow down the development and sometimes they disappear. This is just based on my experience as I have been a victim of some shady ICO's.
In our opinion, advertising is the driving force behind the fact that many of them are victims of fraudsters. scammers buy the most expensive consultants who lead investors. investing from $ 5,000, any scammer buys investor confidence through consultants.
