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?
Yes it "dominates" in oil and even stocks trading, so that is not a big surprise that it will dominate in bitcoin trading too, in fact, it already does that as most of trades are done with $
Yes at this point of time bitcoin is dominated by dollar but not for long. The fact that bitcoin are starting to accept local currencies sooner or later even without dollars bitcoin can survived. We can now buy bitcoin without using a dollar currency, we can use other currencies to buy bitcoins since bitcoin markets are now present in different parts of the world, a localized version. It simply means that bitcoin is no longer backed-up by dollars alone but by other fiat currencies as well and if dollar falls then thats the end of dollar dominating bitcoin.
