Gambling is a bad idea to earn more as you will probably lose it all, quickly.
all of your sugestion is bad
ponzi gambling is very bad way..
in my opinion giving Loans is wrong way, because interest in our religion is haram
(just my opinion no more)
Sharing opinions are good here. That is why these thread is made. Yeah I also know some people who dont loan anyone for interest. But they do it for help. Sometimes if they really have a spare they dont take the payment back.
