Yeah, and quit after a week or so cause they already know they can't catch up with the top 10 anymore. Quantum is about how good you actually play (and a bit how big your credit card is, unfortunately), not about how long you play Main and can afford to x-trade.
Quantum cross-server trading = bad idea
Besides, if you
really have to, you can sell stuff in Main for $ and use that money to buy Q FSS.
