Anyway, investing in ICO is best when the prices are dyed in the blood. It is difficult to estimate the price in these days. If you invest money to potential ICOs, you can earn a lot more than earn from other coins.
Yeah you need to invest on the ICO project but for ICO there is no such town you to need to follow I guess. If you meant to make double the money with the ICO project then you need to go with the ICO at the pre sale time itself.
If you want to go with investing on good project pre sale time is the right time go with your money. So be faster.
