7btc is total wagered, this means worth of my total bets, balance is this with what you can gamble, profits are counted on your first bet, how much are you total in profit atm or how much are you in loss total from first bet. 7btc wagered is small amount, but try to reach 0.18 from 0.0003 btc, so with 0.003 i can make basebet about 0.00005-0.0001 so it takes pretty much time to wager 7btc total lol,
