1. The minimum bet is 500 rubles, and if you are the only one who bet on Ive, then yes, the bank is yours.
2. The maximum bet is 2000, and if you bet 500 and I bet 2000, then I have 4 shares and you have 1, so out of 40,000, I get 32,000 and you get 8,000.
In general, I thought so, it's logical, but it's not specified, so it's better to clarify.
