While I appreciate and understand the big benefits of cryptos, I wonder if and how authorities would let go of their controls and tools to steer and support our economy if and when these tools become more widely spread. I've been in the BIS HQ twice to discuss these things and figured the most likely outcome will be the technology will be used, but not the current forms and brand of cryptos. We will see programmable money, central bank or BIS deposited bank accounts for anyone and new forms of doing business with smart contracts. The banking system as we know it will be obsolete in a few years if the next money evolution step happens. Let's see!
