I missed a citation of Revelation 13:16-18 in "The Gospel According To Bitcoin" by Daniel Sherman and J.M. Bush in the sections talking about CBDC and Covid. Are these not examples of the "mark" in our time?

"You shall not steal". Printing money including taking a loan is stealing because you dilute the value of others holding fiat money. You can read all about this in "The Gospel According To Bitcoin" by Daniel Sherman and J.M. Bush

Hodling does not imply that one should refrain from using bitcoin as a means of payment. Instead, it means not to sell it in order to have more fiat aka realizing some gains. If you do not use the lightning network for payments, you miss out on benefits such as lower fees, reduced surveillance, and uncensorable transactions. It is really unfortunate that, even in 2025, some keynote speakers still claim that Bitcoin payments are unimportant.

Everybody pays the fees they deserve. Instead of complaining about high fees using the Twint payment app the "swiss retail federation" could promote payments with lightning. https://www.tagesanzeiger.ch/anzeige-gegen-twint-das-muesse-sie-wissen-229818778320

Well, I would like to buy the train tickets with lightning. Bitcoin will only be successful if you can use it for daily purchases. On and off ramps are choke points.
