On the potential of the blockchain: “Though I am often described as a Luddite, I am jumping on this creative new train of thought, for after trudging through the sludge of an old and dying system, I find great hope and joy when people come together in a positive effort to improve our way of life. It’s incredibly liberating and the possibilities seem endless.”
