First - You can not get bankruped - but you can have minus account and that is not good....So if you dont want to buy RBN (never buy in game) you have to stay above that limit.
I borrowed 1 000 000 RBN from a friend to level up stadium faster. But yes - I needed to paypack of course after 30 days.

Well - In the beginning its most important to get up to level 5. And dont get suspended. I play in league 1 with 2 teams and what I have understand it is easier to get more audience in that league than in lower.

(Go and shop sometimes if you have money. I did a team of players just for 5000 RBN each and that team is still in league 1)

Great. I did check market but platers are really expensive. My starting teams seems to be doing hood. Won 2 matches out of 3. So i will try adding players if find some good one.

Thanks for tips.
