This is better suited to the speculation thread. The USD price has been trending about 10 bp/day north of the difficulty trend, which is itself about 60 bp/day since June. It is unlikely to hold for an entire year however. There will be lower-order jumps, and they will probably be adverse (mean reverting). In the absence of adverse jumps a 70 bp/day price trend would give us XMR\USD 6.
Looking at those words, I find it difficult to believe that XMR will be that cheap in a year. BTC will probably have another hype cycle in that time, and XMR will probably get lifted with BTC, perhaps to a larger degree (levered play). The size of the BTC hype cycle depends largely on the bandwidth available for fiat to flow into BTC, when it happens. Still, in the absence of informative priors, ceteris paribus, the standardized expectation would be distributed according to the constraints mentioned above. The central tendency of everything under the no-arbitrage assumption is always the risk-free rate. Either you reject that assumption for a particular case, on grounds of differential information, or you limit your discussion to the shape of the distribution.
All of which is just another way of saying I think I have differential information, to the effect that favorable jumps will dominate, and the momentum trend will extend, rather than adverse (mean-reverting) ones, during the coming year. I think the central tendency is better placed north of $6. The distribution is very disperse, so that it contains relatively little information. Any attempt to plan financially based on such a distribution is subject to catastrophic failure.
