I just joined an ICO, is there any possibilities that I will be scammed. They have just collected $5-10 million.
I think it depends on the project and the developer policy. Although ICO's achievements are few, but if the project can run at a small cost, usually the project will continue. Like minexcoin, they only managed to collect less than 300 BTC, but the project continues, and now the coins are pretty good.
Another option if at a small cost is not enough to run the project, usually will held ICO Phase II or extend ICO date, but it all depends on the policy of the development team.
