Bitcoin as a Store of Value is driven by people buying it with the weaker money in order to preserve their purchasing power across space and time. They will be reticent to sell or spend it unless absolutely necessary.

Bitcoin as a Medium of Exchange will be driven by businesses realizing that they would prefer to receive payment in sats rather than fiat, and therefore providing incentive to those willing to spend their sats.

While we currently have a miniscule percentage of merchants who prefer to receive Bitcoin as payment, our mode of operation when buying from them should be to spend and immediately replace, or more ideally to use something like Strike or Cash App to convert fiat to sats as we spend it.

We get rid of our dirty fiat AND the merchant receives sats. Win/win!

As an added benefit, there is no concern about our cost-basis when we spend this way.
