i think it depend on the policy of your country, if your country imposed tax on bitcoin then you have to pay tax on it other wise there is no tax on bitcoin at all.
Personally, I would say that if your outward appearance in life has not changed too much, then wait on the taxes until a year when they are not so against Bitcoin.
yes but as not a single country yet consider bitcoin as legal currency therefore i think there is no tax on bitcoin and when bitcoin will be consider as legal currency then they will put tax on bitcoin,
