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. I find the entire green argument to be bull because from a starting point, the way we produce energy is the problem, not PoW miners using that energy.

But politics follows mostly emotional arguments instead of logical ones. So we should really be prepared to see a PoW ban in the future.

Also, China does not give a damn about the environment. The ban I suspect was more poltical.
