This is very interesting for El Salvador, well, for their establishment at least. It isn't very exciting for a lot of poor people there who lack technology and are very circumspect with respect to cryptocurrency technology in general.
On another note, with all due respect, I can hardly see how North Korea would be doing Bitcoin mining, even undercover. I cannot imagine it... but reality trumps imagination big time. As for Russia and Iran, well, they must definitely mine some bitcoin undercover for certain!
P.S.: Green mining is the only responsible and healthy way to go! Keep up the good work, as usual! :)
