I understand you are comparing the volatility of Monero compared to the volatility of Bitcoin during the last 2-3 months, we are talking about volatility of Bitcoin All-Time compared to volatility of Monero All-Time.
Yes, but Monero by itself is worth virtually nothing. Its only because it can be exchanged for BTC that it has any value. So in order to be less volatile than bitcoin (you can only compare the 2 to the dollar when establishing a BTC volatility for comparison), it would have to correct to maintain parity with the dollar every single time BTC moved in price. This obviously hasn't happened and isn't happening; ergo XMR is more volatile than BTC.
XMR may be less volatile over its lifetime than most other alts, but its ridiculous to say its less volatile than BTC. That's why he isn't recreating his thought process for us in this thread.
