For taxpayers, cryptocurrencies are the most ideal currency because it is not governed by any jurisdiction in any country. Thus, no tax regulation can be imposed to it. Also due to its decentralized nature, there can be non-interference of any financial institution because of anonymity in transactions made by it as payment. In fact, you can evade paying tax when transacting into bitcoin by payment of it.

Personally, if the government of each countries make an institution or mandate a law that provides tax imposition of bitcoin, then we are obligated to pay tax to it regardless of its decentralized nature. Even if it is impossible for it to be regulated under normal circumstances, if the government is really pushing for it then we have no choice but to comply. That is why we must embrace the opportunity while it lasts because once the government interferes, then expect for its price to decrease.
