For some, the analytical challenge of trading might be more satisfying, while for others, the raw unpredictability of gambling might be more appealing. It's like comparing chess to rolling dice; both are fun in their own ways!
I think that trading is more professional and not prediction based but analytical which brings out the thrill in it. People can rely on it for source of income even though it is risky but you can reduce the risk with stop loss which stands out as a major difference for the gambling aspect whose main winning power rely on prediction and luck. Trading is more thrilling for me, the charts are there to guide you into the world of global financial economy.
