If you can resist the temptation and withdraw your profit [or half of your balance, regardless of it being profit or deposit] then it's a better way IMO, the issue is that if you lose the remaining balance the odds of the player re-depositing the profit is quite high..
That's true. It's good to cash out your initial deposit. Atleast your money is already safe. Then you can play with your profit, whether win or lose, you didn't lose all your money. Most of the time gamblers forget to do that or if they remember to cash out, they are thinking that they could win more if they would be betting more and if they could bet more times when they don't withdraw.
then i think this is the same as we play with the base bet and we can save our profit until its enough to withdraw and this is my plan so far and i still use my base bet to continue playing gambling. and if i can save much of the profits then i will withdraw it and i don't think that i can win more in many time.
