I wonder what is the cost of one Bitcoin withdrawal?
Easy, just go to any Bitcoin ATM site listed on
https://coinatmradar.com/ and check their current Buy conditions. Mind you, the information may not always be up-to-date, so a complementary check through the ATM’s contact information may come in handy before actually going to one of them.
Does the number of Bitcoin ATMs reflect the number of people using this service?
There no circulating information that I’m aware of on the actual number of TXs per Bitcoin ATM, and their value per site or territory. I guess that ATM vendors do provide some sort of background when they pitch a sell, but it’s not something I’ve seen around.
In Germany, illegal ATMs were dismantled. What about the above Bitcoin ATMs, are they completely legal?
The information con CoinATMRadar is basically collaborative, where by people voluntarily relay information on these Bitcoin ATMs (i.e.
https://coinatmradar.com/submit/). They do not validate the legality of the installations themselves.
