About these numbers
Node counts are reachable Bitcoin nodes (nodes that accept incoming connections) seen by the BTC Nodes crawler (btcnodes.io, an independent rebuild of Bitnodes) and placed by IP address with DB-IP Lite, so places are approximate. They are not the number of Bitcoin users. Nodes that run only over Tor, I2P or CJDNS have no location and are not counted for any country. ATMs are machines mapped by volunteers in OpenStreetMap. No node address is published.
