There are about 60 ATMs in Germany with which you can buy Bitcoin. There, you pay for the desired amount of bitcoins with an EC or credit card, as is customary at ATMs. Many ATMs where you can buy Bitcoin also accept cash to pay for the Bitcoin. A prerequisite for purchasing Bitcoin from an ATM is the existence of a Bitcoin Wallet address. This address must be entered during the purchase process because that is where the purchased Bitcoin is sent. However, there exist fees when purchasing Bitcoin from ATMs. These fees can be up to 5% of the purchase amount, which is of course much more than purchasing, for example, via the BISON app.
