Yes, on the note that even government ban this gambling practitioner will continue to play and will keep on looking for available venue to bet in, while for those who also supporting it due to their culture or it was been part of tradition they will just keep it alive,and for sure more gambling bankers would love to finance setup like this as they will continue to make money from those people or gamblers that will continue to bet and support cockfighting games.
This is clear because cockfighting gambling practitioners are interconnected and can easily find cockfighting venues. They may also already have a cockfighting schedule, so they must have prepared everything before they went to the location. Gambling banks are also trying to provide cockfighting venues, considering many people still want to bet on cockfighting. And there may be government parties who hide these illegal things so they can continue.
Sorry but i personally do not see cockfighting as a game many people want to bet on as you have said, why do I think this?
First is that, there is no statistics anywhere showing that a lot of people are interested in betting on cockfighting, at least, none I know of, so in case you have such data on your disposal, please feel free to share it with us.
Secondly, take for instance that cockfighting becomes legal in every part of the world, that is, both international and local gambling casinos take cockfighting up and open betting on the game to every gambler out there in the world, trust me when i tell you that betting on this game can only thrive for a very little time, let's say a year to two, and gamblers will start losing interest, why, because the life span of cocks are very little, and this will not allow gamblers to make a proper analysis of which cock stand a better chance of winning the fight before betting, this simply means that, majority of the time a gambler is betting on this fight, it will always be the gambler just guessing, no concrete assurance that he or she is sure of what he or she is betting on.
This can make gamblers lose interest in the shortest period of time, this is why i do not that a lot of people are willing to bet on cockfighing as you said.
