Nah, they just updated web page which said only 8,2 billion is distributed while the truth was that its 28 billion. They just know updated their web page. Before it said 72 billion held, 8 billion distributed. Since 100 billion is created its common knowledge that 28 billion is distributed if 72 billion is held. Everyone knew that. I dont know why coinmarketcap used 8,2 billion in the first place.

The most correct would be to use 100 billion since its premine and all of them are created at once.
