I'm looking at Tzscan's API for the circulating supply. 611 454 213 tez were distributed to fundraiser participants and early backers. About 24 458 195 tez (16%) of TF + DLS funds should now be unlocked. 21 143 856 tez in reward have been unfrozen and 149 845 tez have been burned. That would give us a circulating supply of about 656 906 419 tez. CMC show a circulating supply of 607 489 041 and coingecko/tzscan show a circulating supply of 785 312 978. Can anyone explain what the real number should be and put an end to the current confusion?
You are right that it is shown differently in other sites, for instance, CMC. However, if you look into other coins in CMC, you can see they have different numbers for other coins too. Compare for instance Monero in CMC and in their own website. Not even Bitcoin they are totally consistent with other sites (CMC, explorer). An example for a PoS currency showing different numbers is PIVX (CMC, explorer).
