It'd be interesting to see the BTC price adjusted for M2 supply.

It’s a good point, one that I’d like to see made more often. And not just $M2, but global M2.
I'm not certain I got the math right, but here's the chart. I indexed M2 at 01/01/2009 and BTC price starting at 10/12/2010 (5050 BTC sold for $5.02 or $0.00099/BTC). Besides the initial price, there are no prices for 11/2010 - 06/2014 because I'm lazy and couldn't find easily usable data.
