Set up a Trading Exchange that lets players Exchange Crysta for gill and Gill for Crysta. The value on conversion should always change biased on supply and demand of Crysta to gill.
Crysta to Gill should always be Pricier than Gill to Crysta.
You've essentially replaced "WoW Tokens" with "Crysta", for those more familiar with World of Warcraft than Guild Wars 2.

GW2's in-game cash shop doesn't prevent me from logging into your account. It also has the disadvantage of using a saved credit card if one exists for your account (paypal is pretty much the same) to purchase Crystals. (The 'preview' button appears to have issues online at this moment).
