**Special bonus: from 200BTC wagered you get * 0.002 as rakeback bonus Though i dont understand this but the difference between 200 and 0.002 is quite big.
It's meant as X (*) so if you for example wager 200 btc after having already 200 wagered. you wil get 200*0.002= 0.4
BTC rakeback bonus
I understood now but this will not affect my winning or loss, how much can i use to wager 200btc?
It won't. Even if you are at a huge profit the rakeback will still be paid. As stated in the OP only bets with a profit not higher then 3 btc are valid. you could do 100 3
