I think you're wrong. Both got risks but not same risks. Not only these two but all investments will have there own risks but we need to so choose investment products depends on our risk factor. In share market if you invest in some good company surely you will not lose all your investment but in gambling if you lose means immediately you will lose everything so lot of difference between stock market invests and gambling.
They have the same risks between investing on stocks and gambling. Both of them will have the chance of losing but the reason why people keep gambling is because it is fast money eventhough it has far greater risk than stocks. And stocks you will slowly get your money but it is a have a risk too be scammed by them or if you say that is not possible because they have a good background that means you will get some profit in a very long way. So both of them have plus and minus. This just for us to choose which one do they prefer
It looks like you're very much interested in gambling that's why you're thinking or trying to find plus points from gambling but in reality gambling is not same as investment in good companies. When you want fast money that means it is not a investment but you're just checking you're luck but any real investments need a time to go grow your money in legal ways. It looks like you want a fast money so you chose high risk or almost impossible way to grow your money. All the best to you.
Risk and possible reward are always go paralell. If you don't want to take risk because you are a conservative or cautious player, you can expect less reward but if you are this kind of personality, this reward should be enough. If you are a risk taker, you can handle the bigger risk mentally, you can expect more reward. But this does not mean that if you can expect that bigger reward, then you will get it automatically, because of luck. If luck is against you, you can take that risk in vain, you won't get any reward, but loss. And luck is the factor you can't influence, this is gambling about. Someone wins, others lose.
If one going to try every day their luck in gambling means that is biggest mistake. To try you're head is strong or not, no need to go and bang you're head on to wall because from common sense we should think wall is stronger. Like that, every one knows it is almost impossible to win in gambling (online games) so just use it for fun purpose instead of making money from gambling. For growing money investing in stocks are much better option.
