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.
Nah, leave her alone. She is right. The "volatility" is typically the variance in daily returns, and with that metric, XMR has a higher one. What I was trying to say was not best expressed with the word. Let's move on.
