The ICO investments are riskier but if you at the track records, lot of ICOs have performed well when they hit on exchange and gave returns like 10X to 20X. ICOs investment can give you huge returns as well as huge loss. You must develop some habits like following good influencer on social media to find good ICOs and check them on trusted ICO listing site like ICODROP & doing you own research later on the same. The ICOs market is in boom from 2017 and this year they crossed the total collected funds in 2017 in Q2 of 2018 only. ICOs are like box of chocolate with offers if you invest in good ICOs at Pre Sale you will always have upper hand.
Well they think that ico is the only good quick investment, but I do not think so. Investing in ico requires skills in studying and researching projects.
If the person is just investing then they will not succeed. It takes time to think about the ico project you want to invest. I think ICO will not last long. Because many people feel that they have failed to invest in ICO.
