Usecoin was an ICO which is why it was added. If you didn't already know this, it costs 5 btc for that.
These guys here are trying to get a sponsored spot which guarantees the coin to be on the exchange.
Oh, and you also missed one other thing that Usecoin had that I don't have: A premine.
All the money in the world doesn't guarantee a spot on bittrex. If they require PoD and you refuse I guess you don't get to play. Word on the street is that's their plan going forward. Due to all the scams. Required PoD for listing. And btw I am guessing the dev got 33 blocks of this. Check the wallet that got block 1. The first person to mine a block ended up mining 33 out of the first 63 minted. The first person in is usually the dev. I know the dev will pipe up on a sock puppet or someone else with a motive will say they got them not the dev. I still believe it was the dev and I still believe that dev is carsen till he proves me wrong.
