Cryptocurrencies are not used directly in the purchase of stock, real estate or consumer transactions - this isn't an attack on them - just an observation that private banks used to issue money before central banks existed - and those monies would have been used for those sorts of purchases. Presently cryptocurrencies in use look more similar to those tokens/vouchers companies offer except with a secondary market, esp. the ICO model.
I was pondering at the idea that central banking or any regulation of capital flow in society is a strange topic. Central banks are these organizations - people dressed in suits, they have office chairs and receptionists - but this window dressing as corporation or government office distracts us from what is a very strange topic. You have this complex network represented by a number. What is being said by this? That the Federal Reverse is economic homeostasis and the interest rate represents the equilibrium?
Half the time I think central banks make sense and the other half of it I think everybody must be insane. Seems like we could use the rationale for central banking to perform other activities, like population control. Nobody makes the case for something like that but how is it crazier? They're different forms of capital, right?
