NO. what is in your balance in the end of the day is what you will use tomorrow. for example. you deposit 0.001 btc now . then u reach a profit of 0.0005 btc . stop the rolling then continue tomorrow with a start balance of 0.0015 . then get 50% of your balance as profit again . then stop . resume tomorrow again and again . then in 18th day . you will see that your balance is 1 btc or above .
