HMM BITCOIN IS A CURRENCY!!! AFTERALL IT A GOOD SERVICE WE CAN CONVRRT IT INTO OTHER CURRENY WITH ANY SUCH PROBLEMS!!!
IF you can't convert it, would you use bitcoin?
of course not!
but we can convert it to fiat so it is usable and also a good investment.
but in order to become a currency it needs to be accepted by services instead or as another payment method side by side of cash. and since bitcoin is in its early stages we can safely assume that it has the potential to reach that level of acceptance and stability.
