Armstrong apparently doesn't understand or believe that anonymous crypto-currency is plausible.
http://armstrongeconomics.com/2015/03/14/real-estate-15yr-v-30yr-mortgage-new-electronic-currency-coming/Paper currency will be eliminated and we are headed into purely electronic money. This will be the BITCOIN without the BITCOIN. That is a basic model, which is why they have not shut it down allowing it to survive purely to monitor its performance. Of course those who have used BITCOIN will wake up with a shock when the IRS will hit them for taxes, penalties, and interest on past transactions. They think they have an alternative. That is just silly. The Feds have demanded all data from Ebay and PayPal so that if you sell junk from your garbage on line, they get their piece of the transaction. So you really think they will let Bitcoin escape? They are hunting money EVERYWHERE!
Anonymous crypto-currency and anonymous internet communication is plausible. Bitcoin and Tor are not sufficient.
We have the technology to do it. It is just a matter of implementation.
Btw, I know how to make a crypto-currency WITHOUT A LEDGER! Completely decentralized! (from a transactions point-of-view) Even if they shut down the internet, they can't entirely stop this currency from functioning. I am not revealing my secret just yet. Soon.
