Re: Phew that was close!
Interestingly, Bitcoin, and some other "cryptocurrencies" are designed to be cryptographically secure in a way that controls the supply (there will only ever be a finite number of Bitcoins, Ether is another matter), and prevents "forgery"
The weighting used by BTC where you get your fraction of a BTC based on your fraction of the summed compute power spent is an environmental disaster. They could instead used this power to fold DNAs or Seti analyzing or something, just not heat you need to cool down.
