I am a day old in this forum and am understanding some ways in which one can get rewarded and one of such is gambling, but again, one needs to understand the risk involved.
What are your guides from your personal experience of gambling?
What do you mean by the risk involved in Gambling ? Gambling is 100% risky and there is no other thing in the world which is more risky than gambling. So if you are willing to earn money by gambling, think again. You will end up losing money.
Try to earn money from a better way and only then you can risk some of your earned profit in gambling.
