Bitcoin is unfit for the role of global currency. Firstly, its potential global adoption will be vehemently resisted due to the environmental concerns associated with PoW mining. Secondly, it's the volatility - the global currency needs to be more or less reliable and not swinging like a baseball bat. Lastly, comprehending prices for some cheap goods in sats with all those zeroes is honestly too hard.
Exactly. The fact that Bitcoin is decentralized, greatly minimizes its ability to be used as a global currency. Countries will be reluctant to abandon Fiat altogether in favor of Bitcoin. What will happen is that both Bitcoin and Fiat will live alongside each other for generations. One thing to remember is that Bitcoin was designed to be an alternative to Fiat (not as a replacement). I'm fine with that as long as decentralization wins in the long run. Who knows what the future holds for this exciting cryptocurrency? Just my opinion
