You are right, I think it depends on the number of players, however some see that 4USD is not enough for what is done, but if you look at it from the point of view of participation, you have many more chances of winning than participating in raffles that are held to win cars, motorcycles, or a particular amount of money. In my country it is very fashionable for a car or a house to be done in Raffles, and they are from 0001 to 9999 for an approximate amount of 80usd, so when you have this type of opportunity the probabilities when evaluating it with this modality is very good.
