Chart is useless, you can print a million dollars faster than you can mine a million at todays prices energy wise. They are including band building and such. So how much are the data center entire energy cost in china, they are as large as factories with 1000's if not 10,000's of large tall servers that need aircon systems, lights, and other services. Plus all the people in homes with $100 a month light bill added cost for the bitcoin computer running 24/7 with a vid card that is hot as fuck. This chart is bullshit. Now for bitcoin it needs to run a energy intensive calculations for the purchases not just the mining of original coins which is likely not added in. Crypto cannot also be used when power is out unlike cash. So in emergencies bitcoin is unusable in bad weather when one power line is down crypto is useless. Cash is the only thing usable without a computer now and every. If it doesn't sit in my pocket only then it isn't mine. It's like owning an Amazon movie that never leaves the Amazon servers, not your, rented like crypto if it can be taken from remote location then it never was yours to begin with so crypto is a scam that people believe in like digital owned games and other property. Like having a remote OS for your computer, not yours just leased till they tell you to fuck yourself and walk away rich. Stopped gaming when internet connection required since that was basically saying if your internet is shut off or you can't afford it you can play that game you just paid 1/2 a days pay for so fuck off dumbass is how I read that trend. I was spending good money on games that I played alone but MMO's made me keep that money for myself and stuff I could touch and possess. Fuck them digital assholes and their product you never can backup fully. Like having a Dell but if you format by mistake that OS is gone forever so without a full install disk then you use linux "loving it" or you own a pile of hardware with no OS.
