Do any insiders know something? BTC
Obviously they keep very secure wallets. They could even keep a decentralized version of the seed phrase with different, trusted individuals. So that every trustee has one word exactly and nobody knows who the trustees are except for a select few. Although as far as wallets go, I would not think they use web wallets or exchange wallets or anything like that which might be accessed by third party members. Probably a hardware wallet with extra security.
And if any insiders did know something what makes you think they would post it on here? Boredom? Bragging rights?
