that is pretty cool. i guess it shows that there needs to be either a large price rise, or more quit on sale to be useful.
Right, ideally there would be 'large' buy and sell walls within say, 3% to 5% of each other enough to support a customer coming in without any QUIT, grabbing some and executing a purchase.
At a minimum there should be a large Buy wall, but the customer would have to wait for the QUIT to come in (from other purchases).
This also brings up the question to store merchants. Would they require instant QUIT -> fiat conversion to minimize risk? Or are the store merchants also crypto-enthusiasts that would be comfortable holding BTC, or even QUIT? But to get the product shipped, fiat needs to be sent somewhere.
go QUIT!
