No it is provably fair. All gambling site is provably fair. But you need to know how to win in the game in which the house will not get it back the profit you take from them in previous bet. So definitely you need to know how to play safe. How to stop to bet when you are winning. And play again tomorrow.
Yes I like the way you play. It is game changer of the game in which the house will not probably predict it that you are not addicted in his game site. Control your temptation makes your winning chance higher than being addicted to gambling in which your mindset is easy money that leads to losing your capital funds.
