You could almost argue that Hive is the most decentralized because it is the only chain (to my knowledge) that has already fought with the pre-miner and are still standing. If Satoshi emerges and owns 5-10% of the BTC in circulation and decides to sell it all to Justin Sun (or something more dire)... Bitcoin will not fall as a network... but some crazy shit would go down. There is a big question mark there. Steem had that big ugly question mark hanging over its chain. Hive does not. Hive is not only decentralized, but free from the premine, VC, initial investor (mostly) bullshit.
