The US dollar has been dictating most of the trades world wide from crude oil to anything. Is there a possibility that it will dominate in the trading of Bitcoin?
Well, I think that trading will mostly involve different altcoins and not USD or something like that. People would trade litecoins for bitcoins and bytes and so on. Usual currencies will leave the game field, because they are just to different and are strongly connected to specific countries.
It's universal here, and big countries such as US who thinks their fiat is losing it's value are investing their money in bitcoin because bitcoin moves on base on the demand, and it's getting bigger the adoption which makes the price increase. Maybe we just think US Dollar dominate bitcoin because it's how it's measured.
