As you can see, every global reserve currency has it's lifespan and USDs lifespan is about to come to an end. Which currency will take it's place? Yuan? Bitcoin? Personally, I think it's going to be Bitcoin, the time of national currencies is over. Make sure you're ready when the time comes. BTC
BTC might just be the best option than just going to a country's currency because it always happens every time that a country will be using the currency to oppress another country. Even Francs were enforced in an African land so far away from France that they themselves are not even using it.
If they are going to discuss how a currency becomes a global currency, it will disgust your stomach. But its always been that way even in ancient times when India is the richest.
