Students can make STUT tokens up to the price of the course. The value of the STUT token is linked to the EUR, with 1USD = 100 STUT. So if a course has a price of 30$, the total amount of STUT tokens available is 3000 STUT tokens.
After finishing the course, you can trade up to 50% of STUT tokens to fiat, or keep them to show relevance. So by trading 50% of the tokens from a 30$ course will give you 15$.
The more courses you finish, the more the money you make.
