25k is not enough for a serious project. How have you receive this money? From an investor? Or is your money?
If it is your money for using only for marketing, I would consider investing on Instagram. Facebook is allowing more ads from blockchain projects, and Instagram is the platform with best roi for new users.
Personal Cash Not from an investor. I am totally aware that $25k is too small for a serious project.
