Circulation Supply is higher in my mind. Because Hawala Team main Adress isn´t locked (750k HAT)

There are actually nearly 2,5 MIL HAT.
The first 3 Hawala Team wallets have 1,64 MIL HAT - (i dont think that the 2 + 3 Wallet are locked because 1 isnt)

The Airdrop was only 500k Hat not 1 MIL!
Proof: Here is the Airdrop Adress:

500k from the 1 Mil was transfered to the Main Adress.

Take care guys
