Does this thing allow the instant transfer of BTC to fiat? and all the transaction made in stores anonymous (on the system obviously)?
That's what they claim, and that's what I'm gonna find out. I didn't register with my exact name, so let's see if that causes any disruption. It claims to pull directly from your Bitcoin balance on their exchange.
The real test would be to see if there is a transaction log, as in if where the money is spent is recorded.
