so ... first three holders own 97% total tokens PBT
all people sold after the ico?
Primalbase was only on the Waves Platform at the beginning, they added the Ethereum-Gateway later where you can convert your Waves-PBT to an ETH-PBT token. I think this big holder reserves the token if somebody wants to convert from Waves to Ethereum, these coins should not be on the circulation supply additionally to the Waves token. But I haven't checked this ETH wallet, maybe somebody from the team will answer too.
Right, it's simple. Since it's a waves-based token, most of the supply is still in the waves ecosystem. When someone uses the gateway and moves to ethereum, the supply on the waves side declines. So you have to factor the total supply from waves side and ethereum side.
