There has been a lot of discussion about the site coinfairvalue.com and how it values coins, mostly on the number of txs. A lot of alt coin enthusiasts are really touting this site because it devalues BTC and pumps up the value of alts.
However, since this site does not consider the average value per tx in their calculations, I have to say that these calculations are not accurate at all or dependable. And besides, unless you can find me a “fair value” wallet and a “fair value” exchange, the numbers are sort of meaningless.
