They say that eth is way overpriced. So exactly who decides what is the correct price of a coin?
There is a simple way to determine the tendency of the actual price of a currency: PQ=MV.
Rational pricing theory says that (ignoring risk adjustments), the rational present price is bounded by the expected future price, discounted by the interest rate.
Usually if people disagree about the fair value, it is because they have different estimates of the breakdown of future eventualities by case, or of the probabilities assigned to those cases.
In short: I do. And I decided that ETH is too high, but XMR is too low.
