Definitely Book 2.

I'm not a religious person but I am aware of the legitimate concerns of many about The Mark and while I personally see crypto as a tool for our potential liberation I acknowledge it could also be used as a tool for enslavement. I think it's important for Christians to realise that there is a battle INSIDE the crypto space that they need to be part of. Too many seem to just write off the whole technology as evil and that will just mean the bad guys win.
