bitcoinaverage.com price precision i noticed that from the 13th of feb 2015 the bitcoin price becomes a lot more "noisy" on bitcoinaverage.com:



does anybody know whether this is actually due to bitcoin price movements becoming more rapid, or whether its just that bitcoinaverage.com increased their sampling frequency?
I don't think the issue is that they don't have the data. I think they're just showing the data at a lower sampling rate.

This chart draws data from three locations:


https://api.bitcoinaverage.com/history/USD/per_minute_24h_sliding_window.csv
Updates once per minute, but only has 24 hours of data.
https://api.bitcoinaverage.com/history/USD/per_hour_monthly_sliding_window.csv
Updates once per hour, but only has a month of data.
https://api.bitcoinaverage.com/history/USD/per_day_all_time_history.csv
Updates once per day, but has all data.


Note how the data that goes back further is less precise.
