Trolololo, only recently discovered this amazing work - THANK YOU (and others).
I did a bit of my own work in Excel and came up with this chart, which I think is fairly close (based on 1st of the month values in CoinMarketCap). (...)
I then made a monthly chart for BTC for the last 2.5 years and like the correlation.
Nice !!
But I have to confess I don't completely understand the values for 10 ^ 2.66167155005961 as well as the -17.9183761889864? Could you potentially elaborate or point me in the right direction?
Those are the parameters thar define the log curve.
Reason been - I tried to evaluate ETH and had to move the START DATE from 9-JAN-2009 (for BTC) to 1-JAN-2013 (ETH?) to get an "acceptable visual correlation" (not very scientific I know). This is my best guess at the moment...
I don't know when ETH was incepted, but that should be the start date.
