Well no, he is quite accurate. Aside from the Proof of Work and Proof of Stake technical pro and contra arguments we need to keep an eye on the regulatory side as well. Europe is going against PoW and just because they failed to have it banned this time does not mean they will not succeed in the coming years.
Please seriously consider: what is the value of a cryptocurrency if its whole existence depends on it being supported / allowed by nation states?
In my opinion, one of the main motivations for all this is free money. Free in the sense of freedom. If the ability of a blockchain to continue operation completely depends on regulators, your blockchain is doing something wrong.
The reason why? Because (large) mining efforts are a centralised effort which can be attacked by the government, and easily so...
From my perspective its only a matter of time.
Hobby miners rejoice! Cheap gear and higher payouts, plus more decentralization - what's not to like!
Yeah looking from that perspective, I guess my own subjective view was a bit too pessimistic. In fact, the fact that they would ban and dissolve large mining projects would quite literally be better for Bitcoin. We do need to shake off the centralised parts of the whole. And in the face of pushback from the government would come more innovation and new technologies. Although if you look at China, can Bitcoin be called a door to freedom when your entire internet is monitored and controlled by the government and even VPNs become almost impossible.
I guess we just need to see what the future of blockchain will be. Regulators will not give up, thats for sure.
