IMO gambling is gambling as long as it's purely depending on luck and no support for it on other aspects "knowing methods of trading, best methods and ways to earn, specific market analysis", if the trader doesn't know these then it's merely gambling.
No trading and gambling have a very huge difference because on one side where you are betting on your luck and in investment you are actually investing your money WITHOUT ANY RISK for small profits.
I don't think so because for me they are totally different. Because in gambling we need more luck and we don't need more time to gain profit if we win. But of course it is depending when we win or not. But in investing we can grow our money with our strategy and with our knowledge for us to gain profit in a long run and in this kind of activities there is no easy money we need more patience for us to succeed.
