Many ICO websites have raised a good amount of funds and decided to go scam on the last minute, it's such a shame.
most ICOs are scams now, I suggest this if you don't want to scam, take IEO, but there are purchase restrictions and you have to compete with others to get it, for example in Binance and Poloniex, IEO is sold out quickly there
There are some ICOs that are not scams and are very successful. But Yah, I totally agree with the fact that most ICOs are fraudulent when they have sold a large number of tokens they created. And the risk of investing in an ICO is very high now. So it's not worth trying!
