You can get an iTrader for everything over $5 sold or bought in the BST section. Oh by the way, try to refrain yourself from posting titles like that. It may seem "cool" but it is quite annoying actually.
There is not any easy way to get an itrader. You will automatically get good itrader if you are good and deal legally with other people. So, don't worry about it. - Digital -
Itrader is not just a number, it's the level of trust. If you have positive deals, you will get itraders soon Good Luck
