It seems absurd and at the same time exhilarating at the thought of monero surpassing bitcoin in the near future. It seems possible but not likely.
That can only happen if and when capital controls or other regulatory/enforcement measures are applied to bitcoin transactions sufficiently to make the use of bitcoin undesirable. That in turn can only happen if the volume of subject moneyflows in Bitcoin rises to a level which forces regulatory/ enforcement action. That in turn can only happen in conjunction with a substantial rise in the market clearing price of BTC. Therefore, as an XMR bull, I expect the fiat price of BTC to rise substantially before the BTC price of XMR sees it's most notable increases.
This factor relates to the model term Rm, which I mentioned previously: The proportion of global "white" label moneyflows which XMR denominates. In my simplest rule of thumb for XMR valuation, I make the pessimistic assumption that it is nigh zero, negligible, on the theory that bootstrapping the market cap to liquidity levels sufficient for white flows to dominate price will first require a dark market uptake phase, in which price is dominated by Rn. If Bitcoin is taken up, and subsequently rejected, as a means of evading financial repression, a dark market dominates phase will not be required, however: Bitcoin will achieve the bootstrapping on our behalf.
These bullish scenarios are not mutually exclusive. If they occur simultaneously, the appreciation rate will be a real head-turner, and bubble spike will be truly amazing.
On the other hand, Cyprus spiked Bitcoin, but Greece not so much. (Perhaps because of the grey Russian money in Cyprus being more attuned to crypto.) Which specific cataclysms in the fiat world prompt large flows may prove surprising. Some disappointing failures of XMR or BTC reactions may cause investor defections. (If a large subsequent price response occurs, that is likely to be a very intense run as well, as defectors rush back.)
