That is the wagered amount i guess. Even though it's not then lets take an example
1st Bet Amount wagered 1 btc = Loss
2nd Bet Amount wagered 1 btc = Win 2 btc
So even in this case showing the amount wagered which is (1+1) btc is equal to showing the amount won which is 2 btc

https://dicesites.com/primediceThis is NOT amount wagered. You gave example on 2x, so it's 2 btc, but it's just coincidence. Look:
1st bet - 1 btc on 10x, loss
2nd bet - 1 btc on 10x, win
Won last 24 hrs would show 10 btc, tho amount wagered is 2 btc. It only shows sum of all greens, which is neither amount wagered nor amount truly won (defined as raise on players' profits). That figure means literally nothing.
