Now I am not an expert in gambling but this day was a really eye opener for me, you can never win in gambling. Imagine when you can't win in lotto , soccer betting or whatever you call it, you don't have a chance in slots.
It's gambling, you lose some and you win some. Luck will always be a factor in gambling. If luck is on your side on a particular moment then take advantage of it cause it will not last long. In gambling your loses is much higher than your winnings so don't think gambling as a main source of living.
When you see that a gambling site offers many things, you should understand that it would be fake because no one will give his money easily. I never gamble online because I dont like online gambling. I love traditional gambling but not for making money because I am not regular gambler and just spend my time in happy and pleasant atmosphere.
