Morpheus Titania, a former window shield repair guy and consummate salesman, now lives exclusively using bitcoin, and on rare occasion, cash. I didn't think this was possible, and most folks are surprised to hear it can be done, but Morpheus is doing it and living well. His amazing rant on how he operates with no overhead, no employees, etc is worth a listen, as is this whole podcast.
Instead of yet another interview with a Bitcoin or Blockchain related company, Morpheus the individual is a Phoenix bitcoins trader that seems to be single handedly increasing the adoption and acceptance of bitcoin and other cryptocurrencies.
The ghost of Satoshi Nakamoto and all bitcoin users owe Morpheus a "bit" of gratitude for his service to the cryptocurrency.
