You know what unstable governments in the middle of a revolution don't have? Reliable power and internet.
> Your country was invaded and crossing the border requires you to interact with corrupt guards that steal anything of value you try and get out. Putting your wealth into a bitcoin wallet can allow you to escape with it intact if you memorize your seed words (there was a story about someone in Ukraine that did this crossing the border patrolled by Russian guards).
Sounds like a great way to get rubber hosed to death.
> Bitcoin is deflationary, the coins are limited and scarce, but the currency is divisible. This means they should hold value over time. Fiat currencies are vulnerable to monetary policy of governments, bitcoin is less so. Bitcoin may increase in value in part because other currencies are decreasing in value.
Deflationary, for consumers, is bad. I am also not convinced bitcoin in nearly divisible enough to actually be world currency. (And that's ignoring the fact that it would need something like 7 orders of magnitude improvement in throughput)
