how to determine ico is good or bad, i have a lot of loss, because its price drop when entering exchange, please help me friend
It's not that easy to find a good project. Just like everyone above me have mentioned, you should do some research.
And as for the price drop, we cannot do anything about it. I mean like, a really great project should have a great team and community.
A great team, at least could make the price in a stable states. And it also depends on its pair prices.
