In just feel it's not a good analysis because bitcoin it's calculated pegged to USD and Monero is calculated pegged to Bitcoin, I think it'll be impossible for any coin pegged to a currency to be less volatile than that currency.
I understand where you're coming from but the fact is you cannot exchange USD for Monero so a USD/XMR pairing doesn't mean much. Why shouldn't I also have to calculate bitcoin into euros, pounds, dinars, yen and everything else and then make a mass average for Monero?
In that case all this talk about Monero volatility is a bit baseless isn't it? I mean I can't see how Monero could be less volatile than bitcoin considering it's being based off of it.
I personally have been making all my trades taking into account the price of USD and see the lack of USD pair being a slight inconvenience. If Monero becomes some default coin for the wealthy and black market then thinking in terms of USD makes more sense.
