One of the great advantages of soccer over other sports is that you do not really need much equipment to practice it, other sports require that you have some special equipment that is relatively expensive and that cannot be bought in many poor countries, but when it comes to soccer you only need the ball, everything else can be substituted with free alternatives and you can still practice the sport, while in the case of baseball you still need a bat, many baseballs and gloves for everyone making it way more expensive to practice than soccer.
But to play it, you need to have a big open area which you have to find the goal from one side to the other side. I think there's not that much difference between it and basketball.
Both requires the ball and that's where the game mostly circulates. While in basketball, if it's all/whole court, you need to have the both sides too but in street basketball, you don't need to have both of it. Having one is enough.
I'm sorry but I think you are a little bit off-topic, the thread isn't about which sport is the most appreciated,watched, practiced or chosen to bet on but which one is the most profitable to bet on. I don't think it's soccer because bookmakers are mainly focused on it and are trying to get the most relevant odds for each outcomes to not lose too much money since it's the sport attracting the most money. So you won't find the most Expected Value on soccer markets.
