You are all amazing and every time I read the posts in this thread I admire what a close-knit community we managed to build together around eXch. If you allow me, I would like to announce that among the 16 most active visitors of this thread, a crypto capsule with eXch attributes will be raffled off.
The winner will be determined by the last block mined in the outgoing year (UTC).

Congratulations on the initiative. We will be waiting for your comment.
However, a doubt arose in my mind.
What happens when we try to exchange for a currency that does not exist in reserve?
For example, at the time of this post XMR has zero reserves. If I try to convert BTC to XMR what happens?
