For me a very important is do not let anyone bid more that 100 times for a player in auction, that way people could not cheat anymore to have maximum cash.

In the server of one of my teams, i am tired of seing managers from my level (6) or less with 2,14B In cash, i even saw a bid war and i have screenshots, of a bid war were the price f the player was changing to 2.14B/-2,14B/2.14B/-2,14B.

It is already hard competing with people that can farm or buy a lot of tokens, but whend they can have maximum cash it is completely impossible to buy any good player, they got them all.
