I've heard about this from some youtuber before, but I definitely don't think Bitcoin is the mark of the beast, the mark of the beast can be anything nowadays, digital identity, CBDCs, a microchip that they want to implant in us, artificial intelligence and a long etcetera that may come in the future, but of all the options, I think Bitcoin is the least likely, as it is the one that has been most demonized of all the options.

The mark of the beast is religious and spiritual. The beast, the image of the beast, and the mark of the beast. It has everything to do with the religions, and nothing to do with Bitcoin. Search the Scriptures.

Never even thought about this but it absolutely could be given the bible is actually the word.of."god."

I would have added at the end that CBDCs are (just like in the historical scenario that was cited).
