Interesting piece, I made it until the end ;-)

Personally I am questioning the real effect of futures and derivatives on the price of Bitcoin. I don't think it is that big.

Something else I am wondering is how does/did governments and the tax administration see digital assets like in-game assets, points or credits before? I mean, it is possible to trade those on the open market and they represent value (otherwise people wouldn't be buying and selling it).

Are you familiar with any of that? Companies giving you free shields and swords in a game or some credits to play a Facebook app. And if you want to play more, you'll need to buy credits for a certain price. How different is this from crypto (utility tokens) and how is it legislated?
