Spent months analysing sports betting to come up with a winning strategy. Once figured out, I started betting and made profit consistently. Then, out of the blue, I was getting blocked by the gambling companies. One by one.
For the time that I was able to execute my strategy I made practically nothing compared to the time I had invested in it.
If you think you have a winning strategy and you’re not getting blocked, then you don’t have a winning strategy, you’ve at best been lucky.
