Hive and Cosmos are falling behind because people only care about raping rewards pools and getting airdrops, and don't actually care about the purpose of the chain. Most of the top 20 witnesses on Hive really only care about earning the tokens, not trying to drive growth for the chain. Those of us who actually tried to build were pretty much shunned by the larger whales because of this fact. They want all the rewards for themselves. It's mainly the old guard who ran a bunch of voting bid bots and got rich in the Steem days from all of that scam shit. People basically used to pay for votes, and paid more than the voting power was worth, so those that ran these bots made a killing in the beginning. Many are top 20 witnesses now.
