Well some of the ico are scam but some of them are a gems . so better to do research and invest only that you are willing to loose dont take advice from the others do your own research.
There are some ICO now failed and the price of the token dropped below ICO price, but still possible to make money by hold it in a few month. Will be any times for that token going up and give profit, try wait patient for that. But there are some ICO was give huge profit like Wanchain, so need more analysis and strategies before put money in ICO to minimize the risk.
Better to buy first some trusted coins like ethereum and bitcoin for investing here then don't post like that you don't believe in ICO anymore because there's a lot of ICO here that run so good like when they run AION here in forum and i earn big in that because after a month the price of it go really high actually also your post is not constructive that's all
