I don't think that many girls gamble because of their emotions. They might think it is just stupid to do so and I can't really blame them for that.
No girls also do gambling,yes most of the girls are emotional but all girls are not the same so some girls also do gambling and ever are addicted to gambling,but yes their number is way less than boys in the online gambling world or in real casinos.
Mind me girls is most addicted in gambling than boys. On our society my mother and other mother play cards as there habit because they dont have job. Its there hobby to play gambling. Maybe I guess you are only referring to online gambling which most of man only knows bitcoin.
