Money is been made at this period because so many gamblers will go there to stake on a ram in other to make profit
Betting on this kind of game can be easy to predict by easily judging for the fitness and look of the rams I think, and one thing I am wondering is how is it done that these rams just begin to fight themselves, seems odd. You also said that some of the rams are secretly smuggled to were the ram fight is supposed to take place, how do people who their smuggled rams die in the process handle it.
The odds to win here is high because of limited option and honestly theres a lot of issue when it comes to cockfighting and our own government is working against those illegal activities because it ruin a lot of lives already. In my country
