My kind of thought also..
The thing also is This... The keep the top 20 in the top 20 kind of voting is not that kind of thing buttt I follow the you must have knowledge into the top 20 because their work on the blockchain.
Why even the top 20 why not the top 100 and just steempower based voting instead of 30 votes. That is the real issue... Why smt? We have all ready altcoins?
