I have made a special personal wallet with an added RPC command to know the total number of coins that have been burned in the hive so far.
Here are the numbers :at block height 7920860
Premine : 2 200 000 coins
Normal coin emission ( PoW and the Hive ) : 67 404 020 coins
Coins burned in the Hive : 24 104 103 coins
Coins saved by the community fund 10% : 1 873 022 coins
-------------------------------------------------------
TOTAL : 71 477 042 coins created - 24 104 103 coins burned
=
47 372 939 coins ( current circulating supply )
Interesting fact : on average, 77.7 % of users decide to send 10% of their bee creation transactions to the community fund.
