Mike Adams has been conducting an extensive critique of Bitcoin, the cryptocurrency, generated by a mathematical algorithm, which has taken decentralised money folk by storm. The basic idea is that no central bank can control this cyber-currency, so people have a freedom that normal fiat currency denies them:

I don’t understand how the algorithm actually works, and how “mining’ occurs: https://en.bitcoin.it/wiki/Block_hashing_algorithm
but the one person I know who swears by it, doesn’t either, but has put most of his savings in it. I referred him to the Mike Adams critiques which he savaged, and made him aggressive, but I suspect that Adams would have a come-back. Maybe he is right, and that this really is a cult. Stranger things happen today, by the minute.
