Bitcoin is a means of wealth transfer, no more no less.
The only value Bitcoin has is still measured against real currency such as US dollars. Unless you expect the value of Bitcoin to drop vs USD no-one should be buying anything using bitcoin. Also, if I expected the value of bitcoin to rise, as a seller I would definitely accept Bitcoin as payment to take advantage of uninformed buyers. Seems the sellers are losing now, but that will change because this is still a young market and bitcoin has a long way to rise.
If all of the people here in this crypto community has an outview like you and OP then bitcoin will continue to fail being a currency because instead of posting encouraging topic to attract many users to support bitcoin to hold its value ,what are you doing is making negative issues towards this great coin
