You make it look easy, but that's not what the reality is. You may be winning now, but its only a matter of time before the house edge catches, and most of the time this is where chasing losses happen. You are doing well, and you think that you perfected your strategy, then suddenly the house edge catches you.
I like dice games, and when I was playing dice, I thought I could win, but I later found out that the longer you play, your chances to lose are also high.
