The number of Bitcoin ATMs from September 2016 to September 2019 has increased by over 500%. As of now, there are currently 5,457 Bitcoin ATMs globally. I believe that this is indicative of the strong demand for anonymously transacting between fiat/bitcoin.

If your statistical data is true and valid then perhaps we can make some assumptions that those bitcoin atms were installed in big cities especially located on the first world countries. On third world countries there are less number of machines some have one or 2 compared to first world countries. I guess it is the United States of America that has the majority of bitcoin atms in the world. Let us take note Las Vegas the gambling capital of the world have a good number of bitcoin atm machines and most of it were owned by the former heavy weight boxing champion who is no other than Mike Tyson who has branded 100 bitcoin atms on the different parts of USA especially Las Vegas.
