FC Mobile: Ultimate Challenge (Dream Chasers)

I updated my FC Mobile after weeks now because whenever I play I get matchmaked with people who buys the best players in the game making it impossible to outplay them, since I don't have money to join them I left. Ranked has reset and I can now play with people on my level when it comes to players and that way I can win with my skills and not loose because I have lower players.
I saw a challenge mode and without even knowing about it I tried it, there's a price pool if you win all stages but that price is what I don't know but if I'm able to win the challenge mode I'd show you all what the rewards are but for now I'm all drained out let me go sleep.
