Cool story bro, but most governments would consider that a win -- it pushes the whole thing out of the mainstream.

(edit: A win if the goal was to ban cryptocurrencies.)

You know BTC-e no longer exists and was replaced by a clone called wex, which is linked to a domain in a five eyes jurisdiction (new Zealand), right?

A lot of crypto fans would say you could avoid the exposure once all commerce is conducted without conversion to fiat. To include wages.
