2025 current spiral, 2021 inside that, 2017 next inside, then 2013 - where is 2009, in that quadrant?
There was no price for bitcoin in 2009 and no exchanges, there were informal p2p markets on irc and bitcointalk forum, which is why Laszlo paid 10,000 btc for 2 papajohn pizzas
But what about 2010, 2011, 2012 in other 3 quadrants. Price was so low it doesn't show at all in a smaller spiral I guess?
Price might have been too low and already surpassed the magnitude level (1, 10, 100, etc), the quadrants correspond to 3 months and 2012 looks like it hit 2 magnitude levels single and double digit on the same quadrant? wild volatility during the early days of bitcoin, I was not active until 2013 May or June
