I think that the global trading world system is very fast and needs quick payment support as well, so the potential of digital currencies like bitcoin is very potential to replace the current currency, due to its global nature, can not be interfered by any country, and very safe , and can be for means of payment anywhere without going through a third party intermediary for example the bank, so chances are the future of bitcoin currency will be the best choice for the business actors especially the trade between countries.
