I prefer an investment in an insurance or some form of making money rather than putting my money on dumb luck and gamble with it. Gambling is supposed to be for the thrill of it and entertainment and not for making money. Especially making money online. You can always lose all your hard earned money if you gamble everything.
There is nothing that can be guaranteed, even when it comes to gambling site investment in the long term. Everything has its own risk although that investment may only have smaller risk compared to gamble . Risk is part of the reward and you wont get any reward if you are not risking anything at all
I also think same. Evert moneymaking opportunities like its guaranteed we need to deal the risk. As all investments involve risks, but understanding your risk capacity can help you make more strategic investing and will be given a reward near future.
Not every investment is risky. If you search and do your full study on an investment site, you can find it yourself if it is legal or just a scam. People do not do any research and there only motive is to earn quick and they fall for the trap. Most real paying investment sites wont give you more than 1% daily and those give 10 - 20% are just scams.
Regarding the OP question Gambling with proper planing is not a loss at all and can still be profitable.
