The truth is that there is always that likelihood of losing more than you make from sports betting. I have tried it in the past and discovered that it is not what we make it to look like. Earning through betting is smooth, but it is important to do checks and balances.
It is actually a very good thing for you that you were not addicted to betting and gambling. This is because if that had been the case, you will find it very difficult to stop playing bet because even if you are losing money, your addiction is still not going to allow you quit that very bad habit.
