That's depend on many factors, but personally i think Bitcoin's having real shining future, and it's able to be the future of money sooner or later, especially the price is growing up fast, and the crypto currencies community is growing quickly as well.
fully agree with you. There are many digital currencies online but no digital currency is greater than bitcoin.
Only if will be displayed in digital form for use on the network, bitcoin will demand long, but I do not think that it will become the number one currency in the world.
