shortest periods for price doubling
I don't think it is very useful.
Price doubled in one day:
1. 2010-09-14 Low: 0.06, High: 0.18
1. 2010-10-08 Low: 0.01, High: 0.09
1. 2010-11-06 Low: 0.24, High: 0.50
1. 2011-01-31 Low: 0.47, High: 0.95
1. 2011-06-12 Low: 10.25, High: 24.99
Interestingly, the only two-day doubles start the day before the aforementioned one-day spikes. Only 3 three-day doubles do not include the spikes above.
I meant periods where daily average price doubled
like period starting from somewhere in November 2011 where price was 2 usd , and somewhere around new year when price passed 4
there were a few periods of doubling in first half of 2011, when price started at 0.3 usd and finished at 30 usd
those kind of periods, where daily average price is doubled at the end of some time interval,
so, list should have starting date and average price of that day and ending date and average price for the day
