That idea that Germany makes everything so well only applies to machinery. Germany is falling behind day by day technologically.
The Internet connection is a good measurement for this assessment. If a country does not take connection speed seriously, it isn't moving forward technologically. We can get better Internet connections for free at the airports of poorer countries like Greece or Portugal, than at home in Germany paying 30€ per month.

This is also a country where paper money rules. Germans prefer cash and mistrust credit cards and digital wallets.
Paypal managed a certain level of trust, thanks to eBay. Credit cards are a necessity because Germans travel a lot.
Alternatives to cash are used in case of need, so I am not surprised at all that there are no BTC ATMs.

Even trying to establish a conversation about cryptocurrency you will find yourself in a discussion with the foreigners, because you lost the Germans the moment "digital" or "crypto" was mentioned.
