You have a point there. Playing gambling won't be profitable, while in investment it depends on where you are putting your money in. But when it comes to risk, it is riskier to gamble than investing. The two differ in the way we start and end. Usually in gambling, you start in small, and win big, while in investment, you start small and receive smaller ROI.
But when it comes to this two, I'd definitely choose investment, atleast with that you know the risk that you are facing since you will not invest if you don't have an idea about it, while in gambling, the result is unpredictable and mostly losing.
Agreed, there is no way a person can get rich instantly just by trading, and the HYIP will tell you tah you would get sirious amount of money after investing but there will be no return. The problem in gamling and investing is its always risky no matter what, but I guess it's still good cause storing bitcoin now is risky though.
