bitcoin is being used in so many places throughout the world but it can be so much more. It's obvious that there are so many freelancers in every country. Firms, companies, startups etc.. have a limitation that they can hire freelancers only from their country since they can pay them only in their native currency to avoid hassle of exchange.
Bitcoin is created to open up all the possibilities of trade world wide without any hindrance and to be away from the tight grips of the government and the bankers who are manipulating the financial system and we know what happened and what caused the last global financial meltdown, so bitcoin can be used in much wider scope than some conceive it to be and i am certain we will eventually see that happen.
