So my 25usd June estimate was pessimistic. Probably I should have accounted for the arbitrage of the bitfinex gap. Strangely, all of my evidence-based estimators of XMR f.m.v. indicate that even the current unexpectedly high clearing price is undervaluing XMR. My newly calibrated f.m.v. estimate is 32usd. Probably it will take a while to catch up to that, however, since some sort of profit-taking cycle should usually occur after a run-up.
Perhaps the strongest pessimistic counter-argument in my head at the moment is "sell in May": In a broad asset deflation, everything gets sold, and given current ratios in U.S. equities (valuation and leverage), any summer slump could easily become a contagious rout. But if crypto really is becoming a diversification asset (even in a very small but still meaningful relative to BTC market cap way) that pessimistic argument will fail dramatically.
Anyhow, I am not comfortable reducing exposure here, despite the recent run-up. Usually, after a run-up, I would just shut up (to avoid my loose lips harming people who might sell too much, and miss out on longer-term gains), and would go more into btc with my trading stock, but this time I think it is probably best to stay at the high end of my exposure range. Not only market conditions, but also technical developments seem biased bullish in xmr, while btc seems to be enjoying undue complacency regarding scaling and governance problems.
Yet surprisingly bubbling, why?
