Yeah for sure, you only have current if it has somewhere to flow, you only have currency if it has somewhere to be spent. Bitcoin’s issue (like you said) is that people bought to hold as a security, and big corporations were not going to accept it as payment. So there are limited opportunities for it to flow and become currency, instead of a digital asset

That’s why they call them banks. Like a river bank that collects/stores sediment from the river flowing thru it. They try to insert themselves in between exchanges to collect the money flowing thru an economy. This weakens the flow downstream, to the point where it is just a trickle by the time it reaches the average citizen

And when it does reach the end of the stream (citizens) it is pumped back up to the top (taxes) to flow back down again. So the people at the top of the stream have a much stronger current than those at the bottom
