The accompanying chart displays the cumulative number of bitcoin-accepting businesses for the countries selected in the table. The data is sourced from OpenStreetMaps and is updated approximately every 2 hours.
You can select the growth period of interest from the drop-down, which updates the values in the table. The table shows the ***Previous*** value, which was the number of businesses *n* days ago specified in the drop-down. The ***Current*** value is the number of businesses as of the latest update. The table also shows the ***Absolute Difference***, and the ***Percent Difference*** between this period.
