How long I should wait to get decent profit?
Usually? 1 year?
It's totally random.
Some ico can be done an instant profits for their investors, but some also will never make profits from the investors.
It depends on how good the ICO and the demand of the coins itself, and from my analysis the harder the coins to get, the more valuable the coins will be
There's no certain period for any project to grow or succeed, it's depend from how the project developers build strong foundation and engage
more with people to support their projects.
