It may be impossible to know exactly how many people are part of the bitcoin community, but there’s a new site called bitnodes that is trying to track the number of “nodes” (each representing a server, or a server farm) on the bitcoin network, and it’s turning out some surprising results.

The country with the largest number of nodes, 3,236 currently, is the U.S.; that’s 38% of all the nodes counted so far. Germany is number two, the U.K. number three, and Canada comes in fourth.
