Here you go. I compared BTC to XMR in 2 ways, the first is a lifetime-to-lifetime comparison and the second runs from 5/20/14 - 8/12/14 (I couldn't find price data for XMR before 5/20).
The average % daily change for BTC across its lifetime is 0.84%, with a standard deviation of 0.0713 (this is the "volatility" number).
The average % daily change for XMR across its lifetime (starting on 5/20) is 1.16%, with a standard deviation of 0.1671, or 2.34x greater volatility than BTC.
The average % daily change for BTC in the same time period as XMR (from 5/20 to 8/12) was 0.33% with a st. dev. of 0.0277, which is 6x less volatile than XMR.
So no matter how you want to cut the numbers, you're wrong.
This is a load of crap and you know it. Comparisons have to be made across a common metric (any measure of value that is
not one of the subjects being compared. Regardless whether or not trading pairs exist, you have to establish an independent, single measure of value or the comparison is bullshit). Not only are you failing to do that, but you're using one subject as a base for making calculations on the other. Either you're very stupid or intentionally deceitful. You decide.
