balance 6234 mb (1/2 = 3117mB)
wagered = 98456mB = lvl 6 = 0.9% house edge
first roll: 3117mB on 49%; loss total wagered: 101573mb = lvl 7 =0.88% house edge = -3117mB profit
second roll : 3117 mB on 49% , @ 0.88 house edge win
= +3188.2 mB profit
total session profit = -3117mB + 3188.24571mB

at first , he wagged 98456mB <=> lv6 <=> 0.9 HE he bet half (3117) and lost , till now the profit is -3117 he got lv up ( lv 7 = 100000mB+ , he got 101573 after he bet ) <=> 0.88 HE he bet again and won so it's gonna be (3117*(100-0.88)/49-1) = 3188.24571 => total sesion profit : 3188.24571 + (-3117) = 71.24571 this is my most detailed solution for your questions

Loyce here, I agree ![Cheesy](https://bitcointalk.org/Smileys/default/cheesy.gif) Although you could argue the house edge 0.9% is totally irrelevant for the first roll. House edge only matters if you win. Bonus Solution: X could get an extra 12 m BTC profit by entering the Bet for it Contest Code S1, either one of the bets would qualify. That would bring the total profit to 83.24571 mBTC ![Wink](https://bitcointalk.org/Smileys/default/wink.gif)

Q. X, who has wagered 98,456 mBTC has a balance of 6,234 mBTC at Rollin at the time . He bets half of the balance at 49% win chance and loses (Step1) and then goes all-in at 49% win chance and wins (Step2). What is his profit or loss? Show working. (Step 3)
1 1.00 % 0.00500 m฿ 0 m฿ <<<--- 2 0.98 % 0.01000 m฿ 500 m฿ 3 0.96 % 0.01500 m฿ 1000 m฿
Wager = 98,456 mBTC = Level 1
Initial Balance = 6,234m฿
---> Step 1 (Playing 49% win with half of initial balance) Half of Balance = 3,117m฿ Playing at 49% win with 3,117m฿ (lost it) Balance = 3,117m฿
---> Step 2 (Playing all-in at 49% win with remain balance) Remain Balance = 3,117m฿ Playing at 49% win with 3,117m฿ = +3.18061m฿ profit (win) Balance = 3,117m฿ + 3.18061m฿ = 6,29761m฿
---> Step 3 (his final profit or loss) Initial Balance = 6,234m฿ Balance = 6,29761m฿ Final Balance = 6,29761m฿ - 6,234m฿ = 0,06361m฿
