I think that we are currently looking at US and Russia as countries that are producing the most of the slapping content, and those are huge markets that can facilitate gambling and not be worried if other countries catch up or not.
We will see it later. While the slap tournament is available in the US and Russia, people can watch the slapping tournament on Youtube.Actually i believe that this is not yet considered as sport because what is the skill on this?
Does the old times declared this as sport?
In the other country, that will not call as a sport. Maybe the player needs to improve their strength to have more power to slap their opponent. Maybe in the old times, that is not called a sport, but we do not know what will happen in the future.Does the old times declared this as sport?
it is not about whos brutal or not, But what is the purpose and who are the audience?
The purpose is to search for other entertainment that can give us more fun. The audience is people who enjoy the game and they willing to spend their time waiting and watch the tournament.The small market of slapping tournaments is what makes it difficult for bookmakers to make bets on it I think. Whenever I watch videos on the sport than I notice that there is no real weight or height category. The difference between the athletes is quite substantial. And it seems that the heavier guy always wins, except if there is a low shot. So for this to turn into a real betting sport we need more contestants, fans and also more rules.
Maybe right now, the market of slapping tournaments is small, but we do not know in the future because if there are more promotions about the game, maybe that game can grow. The bigger the player will have big power, but that will not always like that because the small player can have a big power if they can improve their strength.
