First watch this vid.
https://www.youtube.com/watch?v=3LSBZtL_sLsCrypto is incentivising people to destroy the planet.
At the moment the world is focused on getting rid of plastic, I'd say crypto is what we need to get rid of next.
If your crypto isn't green it's going to be taken out and shot. If your favourite coins don't destroy the plane they might have a future.
In the video I understand using monitors to run his crypto farm makes it easier but he should seriously consider an alternate solution. That would save more electricity. Additionally, I feel like on the grand scale of things Its causing more good than harm. When it comes to destroying the planet you need to look into waste and global warming. Not crypto learning :p
