Everyone needs to do his own research on what and where to invest, I have a lot of friends who hit a jackpot finding one or two good ICO, the ratio I believe is 8 to 2 out of 10 so investors and bounty hunters need to diligently check, where to invest I think it's more safer to invest in IEO than ICO.
its really hard to look for good project your friends is really lucky to discover 2 good ICO out of 10
