Wait, I trade in the bitcoin market, so I am a "market trader". But because I don't trade paper promises for other paper promises, I'm not "real". So am I imaginary?
By real, he means a trader in markets that have a long, established history of more than the 4 years that btc has. Stocks have been traded since the 1700's. Technically commodities like gold and iron etc. have been traded since before christ lived.
Not that anyone cares, but I have traded stocks since 1995.
