Currency is language, and speaking a foreign language is hard
Bitcoin should be spent as cash. That is the original intent of Satoshi Nakamoto for bitcoin, and also the continued design and effort by Bitcoin SV (BSV).
In fact bitcoin should be spent much more commonly, frequently and ubiquitously than paper cash.
However, for a practical reason, it should not be spent on the surface, but rather be spent behind the scene, almost invisible to regular users.
