I am writing bachelor thesis. I need to include a graph on "how many shops or companies accepted BTC". Do you know where I can find historic data or a graph for this?
For example you can look at this site. It has a lot of shops who accept bitcoin, but I don't know if it's complete up to date. It does not have a graph, but you have some rough data (498 pages with 10 companies per page, so ~5000 companies)
