From the past to the present, cockfighting has always been a popular activity among people in my country, even though it is actually banned by the government. They usually do it in secret and not openly. I don't know for sure how profitable they are, but considering its continued existence and widespread practice, I suspect it still represents significant profits. I have also often encountered this type of gambling on several Asian online casino sites, but as far as I can remember, I've never been interested in watching or betting on it. While it may be interesting to you, I personally find this kind of animal fights unattractive, especially those involving death. I find it better to watch boxing or UFC matches, as they still have some important rules to avoid danger, especially death.
