That's definitely one of the things that you can consider when you are talking about trading and if that's what you have experienced so, why not?
For me, the people who are earning a lot are not so noisy about it and just keep it in a low profile unless it's an enormous amount of win and needs to be televised or something.
Because there is nothing for them to prove in public that they are earning and for their safety from hackers, they keep on silent and continue trading.
And I know that trading is really profitable to others but it is also a disaster to others too. It is certainly hard for beginners to earn a profit which I see OP had complained about his experience from trading.
