The problem of people, is that they only look for the token price, and not for the market value.

I have 2 15T youth players in my main team, fast trainers, they are now both 5* and one is very near of the 6th star.

Token price is random like most things in this game, you can have a real fast trainer for 15T and a slow trainer for 24T.

One of T he player that cost me 15T on day 6 after 16 days i got a player for 24T with lower market value, and at that time they where both with the same quality.
Token price totaly random.
