I think, perhaps, merchant support? Cryptsy can theoretically provide plenty of volume right now, increasing the consumer base would probably be the best thing at the moment.
Cryptsy ?
https://www.cryptsy.com/markets/view/183What exactly do you expect merchants to do with the coins they receive? Tank the price to 0?
I mean that cryptsy is capable of scaling up easily (access to a large number of markets and many users (who often do lower the price of new arrivals because of the often large initial sell volume)). I believe that we need more merchants to accept execoin to increase the number of 'average joes' involved (more people who don't necessarily mine, but rather use execoin like cash or a credit/debit card) for everyday purchases. This will lead to larger buy volumes (we may have merchants selling to convert to cash; but if more people keep buying, that can be overcome). I will admit this is a bit more of a long term goal.
