It's funny how you say you've never heard of this before, but you went directly to this inactive, buried thread as soon as you joined the forum, and quickly decided Christians using currency are engaging in sin.
Can i ask how that came to pass?
I did a google search on this topic after seeing it on another forum just days ago and realized that it was posted here as well. I was looking for more information on this.
I was not convicted by what fiat currency could represent, but by how Christians are NOT supposed to engage in evil or support evil practices. This topic simply served as a reminder of that godly principle.
