thus viewing bitcoin as a monetary store of value. The paradox is that the value of
bitcoin to society is its use in trade (to simplify somewhat) and that no coin can
claim both these features.
Not miners, just holders. Miners nowadays have to pay huge electricity bills with fiat, so they necessarily sell at least some part of their mined coins, so the coins end up in someone else's hands. Regarding the functions of money being antagonistic, I explained this in another thread:
To be a good store of value money needs to be appreciating (the more the better). Conversely, to be a good means of exchange money should be depreciating at a slow (and low) but constant rate. The former contributes to hoarding while the latter to spending. Hoarding and spending don't live well together and are, in fact, mutually exclusive. In other words, you can't hoard and spend the same (amount of) money at the same time...
But you are welcome with your own take on this
