This is not what is going to happen in reality
Unless Lightning Network gets activated and transactions become as cheap as dirt. Bitcoin price surging means that more people buy bitcoins, and that could be supposedly construed as Bitcoin expansion or adoption (provided it is not the old dudes buying new bitcoins, of course). But will it change anything in respect to Bitcoin as a speculative asset versus means of payment dichotomy? As to me, this is unlikely. In other words, higher prices themselves don't contribute to Bitcoin being adopted specifically as a currency. In fact, they should rather be expected to work in the opposite way
