I can understand what you’re feeling because I too get envious each time I see such winnings, and what makes it worst is despite how hard I try I can’t replicate these type of winnings. Also I agree that we all should get inspired from these winnings, and not lose hope because someday it’ll be our winnings that’ll be inspiring people.
Being envious in gambling or trading is bad because it makes your emotion is unstable. Consequently your decisions can be inaccurate because you do it emotionally.
I don't know how about the others but with me, control emotion and decisions in trading is easier than in gambling. But they are both not too easily. The best is don't gamble, don't trade. Invest and hodl.
Gambling is good if we do it responsibly and just for fun. If we consider it as way to get daily income, way to get rich, become millionaire, it's wrong.
