It's perfectly safe.
porcupine87--it has been suggested that the markets be re-sortable on the client side, alphabetically, by volume, or whatever else. Making them alphabetical would be a good start, though.
About the volume not adding up--oops. I never used that feature on exchanges, so I didn't realize that it adds up the volume, but that makes sense.
good. Another thing: When I want to buy Q2C, and I have 0.5btc, I want to click on that 0.5btc and get the number in Q2B according to the price. (when price is 0.00001, the amount would be 50 000). At the moment I get an "infinity" bug.
