another estimate
87.7 TWH per year for bitcoin 2020

" Based on the underlying algorithms, current hash rates, and suitable mining devices, we conclude that Bitcoin accounts for 2/3 of the total energy consumption, and understudied cryptocurrencies represent the remaining 1/3"

I think this model deserves its own thread. I was using another thread but I want to focus on this model. Some experienced users don't think it is very good but I want to follow it for a while and see. Because there is conflicting opinions on its value I decided to keep it off the main melting thread and it doesn't really fit elsewhere. To get started if you compare 2019 on 6/25 and 9/25 final area roughly conforms to anything black or thicker on 6/25. I would like to see if 2020 follows the same pattern. In a few days I will compare other years.
