Bitcoin is made to be a currency so why the hell does the government even have tax on it? It's not some kinds of product. It's money and the countries which abolish VAT for BTC are the ones which are not high right now
If the US and Europe treat bitcoin as a currency, other countries will follow. It is just a matter of time that other countries will adopt the same approach.
Not exactly the case here. There are more major players out there who don't usually follow EU and US legislative process, mainly China and Russia.
I wouldn't be surprised that these countries followed different path just to be different from Western World.
