I believe this could be a serious good coin, however at your website you promote your build from Seattle and even shows bittrex on a map... when does dragoncoin come to Bittrex?

Whenever Bittrex chooses to list it. The team's legal advisers have told them not to solicit exchange listings. Bittrex is following Dragonchain on Twitter though, so we may see it listed there at some point. If you want it listed on a big exchange, vote for it on Binance, they have more volume than Bittrex.
