the roadmap, the future investment, and sometimes the idea of creator is a brilliant.
for me invest at ico is a unique way, we dont know the developer will do it or not, but sometimes we need more than 2year to gget big revenue like ethereum.
This time a lot of people are seeing the icos as the place to trade their money for huge profit, because after the token already listed in the exchange site and there will be a short pump at the early start.
