See this one is really strange to me. Blocktrades helped do some stuff in the beginning with Steem and made a huge pile of tokens. Now he is being paid directly from steemit for something, not sure what.
And his team made the SPS system for $50-100k, whatever he quoted, yet steemit doesn't want to work with pretty much any other developers.
Blocktrades is there because he is in the old boy fanclub.
With all that said, the exchange he runs is useful, just not sure we need his company also siphoning from inflation.
He does participate in steemit slack.
