Tax system differs country to country. In general, receiving as payment for goods or services is taxable income in most common scenario. As long as you are not converting into fiat and either holding or using it, will not trigger taxation in my opinion.

Governments will do almost everything to maintain increase tax revenue of course. They will clamp down on individual BTC users if they expect a positive return from it. The bigger the user base of an exchange, the more likely its users will be subjected to taxation related surveillance.

Personally I have no sympathy for BTC sellers and I think they deserve some punishment, because selling BTC for fiat money is an act of supreme stupidity... Why do you want to own fiat, when you already have the best money in the world? Use your BTC for direct purchases of goods and services and you'll have no problems with taxation at all.

ya.ya.yo!

It's already being done my friend.... Governments in certain countries has already forced BTC exchanges to adhere to KYC/AML regulations and this unmasked some anonymous users. Do not forget that

most retailers work through payment processors, so tracking can be easily done through these services. You will not sign up with these services without revealing your identity. Once they have your

personal details, they just link that to your tax details and everything operates like normal, as if there were no anonymity at all.
