The answer will be very varied and relative, depending on which type of sport you prefer. there are many, gamblers who are experts when it comes to MMA fight analysis. on the other hand, football is the more popular sport so chances are, more gamblers are betting on football betting. but basically, both have the same risk of losing.
Talking about MMA betting, I don't have the capacity because I'm not good at this betting. but for football, at least I have a long experience related to betting on sports. and if we compare, in fact there is nothing that is easier to predict. because after all, we only predict based on data, statistics, etc. also, it doesn't seem that much different from MMA.
In essence, before we predict. of course we will analyze it first, too, looking for as much up-to-date information as possible to be our reference material in betting considerations. then summed it up, became a prediction. related to the final result, we leave it to the two teams that will compete.
If comparing which is more profitable, betting on football or MMA. the answer is the same, if you win the bet, you are lucky. as simple as that.
