This is a great read and short podcast about the future of blockchain technology. The main focus is on "payment providers" and how they will develop the infrastructure. There is certainly a need for a stable platform for crypto use adoption. I had hoped by now that I could buy groceries, gas, or services more easily with crypto. However, due to the lack of uniformity in the crypto industry, this seems to be a long way out.
