Hello @d5000,
There are more variables in the fair value equation than the transactions rate. Coin A having more transactions per day than coin B does not imply fair value of coin A has to be greater than fair value of coin B. Things like the Total Discounted Supply, the velocity of money ratio and the basket shift are fundamental variables in the determination of the fair value of a currency.
With regarding to Stellar Lumens, there is indeed something strange with the data. There seems to be almost zero value in all of its payments transactions. I will temporary remove it from CoinFairValue until I can clarify what is going on. Thank you for notifying.
EUR shows as having a higher fair value than USD because their basket shift is 2. It means that a EUR trade, on average, is in exchange for a good or service whose value is double the value of the average one in USD. Nonetheless, keep in mind that fiat data is very sparse, so there is more uncertainty in the calculation of their fair values. I notify it within the website in different places.
Answering your last question, the reason is not that there is any bug in the formula. The reason is that before I was calculating the fair value
imposing the following future assumptions:
- If two currencies are competing with each other, they will be competing for the same basket shift and, therefore, it makes sense to set the fair basket shift to 1.
- If two currencies are of the same nature (no staking), humans will have the same willingness to trade them in the future, when they are settled currencies. Thus, it makes sense to set their velocity ratios to 1. For the case of staking cryptocurrencies, I was assuming the collateral had a much lower probability of being moves and that allowed me to set an upper bound to the velocity ratio.
Now I don't make those assumptions anymore for several reasons:
- They are not very neutral, because they assume equality of market niches.
- They are not very reliable, because there might be more reasons than just the staking incentive for individuals having a different willingness to trade a their savings if they are denominated in one currency instead of another.
- They do not allow for comparing, for instance, Ethereum with Bitcoin.
And what I do now is I measure average of the basket shift and the velocity ratio of a pair of currencies and I this average as an input in the formula. This means I learn how a currency is being used instead of assuming how will it be used.
Anyways, I will add a feature (the fair value calculator) which will allow the investor to set all kinds of hypotheses on the future and use the fair value formula with these hypotheses. Anyone will be able the get their one fair values based on their one assumptions.
My apologies for the late response. I had a flue this week and I didn't use the computer at all.
I hope this clarifies all your concerns!!
