Did he really deposits only ten dollars? I highly doubt. One of gambling challenges participants once wrote that sometimes to win big money, you have to spend even bigger money.
Hahaha, Even most people only know that I made a big profit just by making a one-time deposit. Most don't know what's going on behind the scenes, how many times have I made a deposit and how much money I have burned.........
I'll show some of my deposit last week:

See that, I had burned more than $800 before I deposited the lower amount, do you think I always succeed in withdrawing after winning the competition? I don't think so

If you are addicted to playing slots, I believe you will find it difficult to click the withdraw option. @bitinity am I right?

That's what gamblers are experiencing behind the scene they deposited lots of money and most of them they lose it. Its really hard to withdraw some of your rewards, because you are still thinking to continue gambling, anyway that is still a good reward and I believe you are still making money in gambling because you wont continue if not and I know, you know what you are doing. Congratulations for all the competition that you've won, a real gambler indeed.
