If you have the conditions to have invested this, I will disregard that you don't need this money! If you considered any contribution before investing in this ICO when something did not go well, I don't see any problem in you putting more money into it, because I'll assume that you have the details of this team and that this project is so good and that it has not so lucky in a market absorption! Either way, take this money invest in financial education and you will hardly have these problems.
