Money Glitch EA FC 26?

Hello everyone! 

I found a interesting glitch/bug in ea fc 26. 

When i go into the rivals modus and left directly after the player search, i got some coins. 

I repeat that process 2-3 times to look if i got more money, and i got it.

I closed the game after the process and restarted the game. 

After the restart i lost all my "earned" coins, but i dont know if you can use the coins, after the bug/glitch abuse.

I hope i could help a little bit 

greetings Micky
