Making profit and winning B3 are 2 different things. So your whole arguement is wrong from the start.
There are several examples of players that won b3 and they are from a SMALL country. Unless finland or belgium is considered a consistently top basketball country both in reality and in buzzerbeater with 500+ users in the past 5-10 years
Both of these winners had an organized plan behind them and they took full advantage of their better economics, either you see it or you dont , it is not about your opinion or mine it is about facts.
Unless I see differently, I will believe the screenshots I have seen from a big and a small country depicting their economics.
So feel free to share your economics. I have no problem doing so.
