The reason why Bitcoin is a mystery for many people is exactly because of this ^. Bitcoin is NOT a currency. It doesn't position itself as a currency. This fairytale is long gone, forget about it. Bitcoin is a store of value.
It cost $7.6M and took five years to repatriate 53,780 gold bars worth $27B back from the US to Germany.
It's >1000X faster and >10X cheaper to move that much in Bitcoin , even accounting for N>>6 confirmations.
Bitcoin doesn’t position itself as anything.
In other comments, though, you can see people are still defending its usefulness as currency.
Your example is a bit strange, by the way. Transatlantic bank transfers in your currency of choice have been a solved problem for decades.
Ok then. It can also be stolen or lost more easily, though.
The volatility concern will eventually go away. Volatility represents people's opinion about Bitcoin. They don't understand it yet. If you look into history, you'll notice that pretty much every new invention goes through this phase. People's first reaction is always the same - "nobody needs it, nobody's going to ever use it".
