All the chart we've made.
A polar chart would have been meaningless back in 2011, particularly where 360 degrees represented 4 years.
This is interesting. At the moment (11th October 2021) we had some ATH (all time highs) earlier in the year. See where the other ATHs occurred in the 4-year cycle? I'm not predicting anything but another ATH to maybe $100,000 wouldn't surprise me.
On 12th October in 2009, NewLibertyStandard bought 5,050 Bitcoin from Sirius for $5.02, valuing each Bitcoin at 0.1 cents each
Yes, we can all look at the polar charts now but look what information there was then!
