Thing is, that if it's 10 exp per gold it would still take 14,569,313,075 gold to do that.
Jumping from 1 to 31 would take 889,240 gold, so it's impossible to do it for profit by selling the loompoints you get out of it.
Jumping from 1 to 36 would take 28,455,689 gold. I have to admit, that is extremely low for what you're getting out of it. The gold charge should definitely increase exponentially as you reach higher levels.
Another is the cap solution, that Wiltzu brought up. :P
Lol that means I could level my character playing trader 10 minutes per day, awesomeness
If you are good? I doubt you would make a lot of XP on long term...
