A Bitcoin Heatmap is a user interface that allows you to see the distribution of Bitcoin nodes around the world. The map is color-coded to show which countries have the most nodes (green) and which have the least (red).
You can also see how many nodes are online in each country.
The heatmap is useful for two main reasons. First, it allows you to quickly see which countries have the most nodes and which have the least. This is useful for finding areas of the world where Bitcoin is more popular and where it is less popular.
Second, the heatmap can help you estimate how many nodes are online in each country. This is useful for finding areas of the world where there are more potential users of Bitcoin.
The heatmap is based on data from Bitnodes, a website that tracks the size and growth of the Bitcoin network. The data is updated every day and includes information on the number of nodes in each country.
