It depends on the psychology of the person himself. And it does not matter where such a person turns out to be, in a casino or trading on the stock exchange, his views will not differ from this. In this case, he will trade exactly as if he is playing in a casino, betting on red/long or black/short.
I agree. People are treating both gambling and trading in similar manner just because of their own psychology.
If they are caring their financial things then definitely they will find skills to distinguish between trading and gambling. But, most people are lazy but greedy at the same time which is the reason they will never get time to develop their skills but going for trading how they are gambling and keep gambling for easy money.
