Governments will always find a way for you to pay taxes. The blockchain is such a disruptive technology that they can't regulate. Therefore they will want taxes wherever they can get.
If you know anything about money than you know that owning euros, dollars, etc. is to own a debt, Whilst owning crypto currency is not a debt but an asset. The fact that the government is not involved in this ownership of crypto coins frightens them.
I suspect that if we hold long enough there will be a way to pay straight up with cryptos rather than banking in fiat and paying ridiculous amounts of taxes. I'm talking about open markets like BitBay integrating together with an anon coin like DeepOnion, which not only hides the users' transactions, but also the users themself. These technolgies could provide a way for us crypto investors to maintain the freedom that we used to have before regulation came into play.
