I think one of the key issues at stake dwells upon the concept of hope. Where does our hope reside? If, as a Christian, hope resides in the free market system, inevitably, it will fail. All systems fail. All systems, apart from the kingdom of Heaven (which truthfully is more akin to reality than any type or sort of system) will fail. The end game isn't as much about the apocalypse, as it is about the second coming of Christ. This is where our hope, where our vision, needs to be founded upon.
Saying this, I am constantly torn between being a "watchman" and working "simply and quietly", living as an example through action, as Paul puts it. I think different people are called in different ways in regards to the gospel.
Augustine said that whenever there seems to be a contradiction in the Bible, if one takes care to truly search through both passages, deeper revelation will be shown to them. I'm still searching, asking God who I am in relation to this world I live in. Am I to speak out? Or am I to live quietly, exemplifying Christ, through the Holy Spirit that lives in me, living day to day? Is it supposed to be both?
Saying this, I'm not really worried about crypto currency being the devil's handiwork. A single currency will undoubtedly arise. All it takes is one huge world market crash and bam...there it is. But as I said, that which our focus is settled upon dictates how we live and act. I'm currently choosing to look at those I can impact around me. Perhaps this is simply a specific season of life I'm living through. Also, the Bible blatantly explains that we will be held accountable for the things we accept, thinking they aren't that bad.
Your article certainly made me a little more aware of this issue, of what it is that I'm not only accepting, but investing into. Thank you. I so look forward to more posts from you.
I wrestle with all the same issues and have reached similar conclusions.
