I agree. I mean, in these day and age where things are getting more modern and modern, hearing about professional gamblers is not already new to our ears but it will always struck us how did they manage to keep their financials and career on the up and up. I know it's not that easy because there are no guarantees in this space and our chances is much lesser because of the fact, still there are some who people are successful on their path and I admire them for that.
If you're a winner, the bookmaker will eventually restrict your account. Therefore, it becomes necessary to create multiple accounts.
Conversely, if you're a loser, the bookmaker may offer higher limits and bonuses.
That sums it up.
To make it easy to understand, what they are doing is hating winners and loving losers. The reason they are so profitable is that the majority of gamblers are losers. This is normal, I suppose, because they are the ones running the business. With this advantage, they will certainly win in the long run.
One of the main reasons they become more profitable is that we gamble irresponsibly. There's a saying that you should gamble based on what you can afford to lose, but sometimes we go beyond that. That's stupid.
