I still believe in ico s because its the quickest way of making profit but yes there are so many scam as well thats why you need to do your research before you invest money
But in the moment I have stopped believing in the ICO project. So I think you should not invest in them now, as ICO prices are always higher than trade prices. Many people have bought and held after a loss. That is what I see today, so I usually decide to buy the famous coin such as ETH, NEO, DASH, BCH ... etc.
