No, it's not a good time to buy Ico considering this bearish market , any Ico you have in mind that you wanna buy just wait for it to hit exchange, dumpers are surely gonna do their work. Then you can buy after dumping, I'm talking from experience, most of the ico tokens I have are from exchange, I bought below Ico price and they are solid projects, majority of them always hit etherdelta or idex before going to a major exchange like binance
