As an extremely bullish XMR holder myself, I can say that this very unlikely to happen. Monero simply won't reach the same popularity as bitcoin due to its features (anonymity, for instance) and how "cautious" exchanges are around this coin. That's why it won't reach the same mainstream level as Bitcoin, therefore, prices won't go as high as 1 BTC. 0.1 in a few years would probably be more than fine (and yet it still sounds far-fetched to me lol), but 1 XMR = 1 BTC? never in a million years.
