Right now it is pointless to partisipate in ICOs. Almost all coins go under ICO price after entering the market and are floating there without signs of life. So, it is more profitable to buy them from exchange than during ICO.
But it is important to keep an eye on upcoming ICO in case some potentially interesting project will show up. But now more than ever, projects for investment need to be selected with extreme caution and care. After all, it is better not to earn additional money than to lose them.
