Following consensus across six independent snapshots verifying the state of EOS ownership, data crunching has revealed only 10 addresses hold 496,735,539 EOS tokens or 49.67% of all one billion EOS tokens.
Some 100 million of that is held by Block.one, the company behind EOS’s ICO and the first code version of the protocol. That gives them, on top of the $4 billion worth of eth they have raised, another $1.5 billion in EOS tokens.
