The stability of the fiat depends strongly(!) on the country/fiat.

FFS, Turkey has an inflation of 70%. Turks are traditional gold bugs (for a reason), even they see the value of Bitcoin (high adaption).

And I am not talking about countries like Argentina and so on.

And then: ever tried to send money international without owning a bank account? Like in 3rd world countries? Or even with a bank account? It's a mess, you pay high fees to Western Union or you have to find someone "eligible" enough to have an account in that country, plus state fucking you (taxes, observation and so on).

For these people Bitcoin has a real good usecase.
