If there would ever be need for a global reserve currency Bitcoin narrative and activities would pop-up, since a soverign-free, algorithm-based alternative would be more stable and trustworthy and perhaps this would be Bitcoin. This goal would soon be actualized especially as Bitcoin is not too volatile and is widely progressing to be used as a universal settlement token for trading, to be used for contracts even between countries, organizations and persons etc.
I believe in the nearest future businesses and sovereign powers will give up their preference for Fiat, and when this happens it would result to Bitcoin earning general global recognition as an international trading currency that embody trustworthy transactions.
I think as a alternative currency bitcoin will be a great currency and as currently it is already becoming a currency that anyone in the world could use and also we could also make a transaction anywhere all over the world. Surely as alternative or reserve currency online this bitcoin could easily be the best , but still need to implement in the market since it doesn't have a lot of assets.
