You should not give up to get money from the ICO. I am concerned about what happened to you because you are a victim of ICO fraud. If your country is a country that allows transactions with crypto currencies then you can report the development team to the authorities. Besides that, you can make viral news to cover all access the development team is doing bigger fraud. I am sure if the developer team is viral then he will ask for your help to restore his good name so this is an opportunity for you to be able to withdraw the capital that you have invested in the ICO. In the future you can learn from experience and be careful in making decisions.
