Suggestions

This suggestion reminds me of the Energy Depot system in the game Spiral Knights, where players trade premium and in-game currency. It allows for an instant trade in either direction based on the current best offers in the player market. Alongside the system players are still able to exchange currencies by posting offers. In-game currency is taxed in these exchanges.

I found it a very convenient feature when I played the game. I'd be interested in seeing this implemented in some form.
