Are bitcoin taxable? I think its hard to impost taxes (if by chance), since it is volatile, value is not permanent and steady that make it difficult to determine its value and possible income.
Yes currently it is not taxable but in future when bitcoin bitcoin will turn as legal currency then government may impose tax on it. for example Japan has turn bitcoin as legal currency therefore i think that they may also have impose tax on bitcoin income.
Most Bitcoin holders make money by Bitcoin, and I think your bitcoin holdings are not taxable (at least for now), but whenever you sell bitcoin or use bitcoin Buying things, are in the accumulation of taxable income.
