Everyday my friend gambles with his money as same with his life and he always gambling throwing away his money for nothing but losing and the worth part of it is he owes me money 
Throwing away with his money for nothing is like you are getting nothing no benefits and others first thing if you really want to waste money then make sure at least you can make money with it and if your friend really can't make money with gambling then ask him to stop playing and learn more about trading instead.
