You can't control what other people do. Also you can't avoid exchanges forever. People aren't going to keep mining with no way of exchanging their coins for btc. If this coin wasn't on an exchange soon it would die. The asking prices in the exchange forum have been dropping already because it was looking like noble might not even make it to an exchange with so many alt coins being released. You should be happy it's on an exchange. Its a step all coins need to make to become legit. Once you are on one exchange the others will follow. coinmarket.io is small potatoes and low volume. When noble hits a higher volume exchange the price on coinmarket will be meaningless. Its unfortunate that some guy decided to sell 600k at 39 satoshi but once that sells the sell orders are looking pretty thin afterwards so the price should go up.
Thank you, this somewhat reflects our opinion on the matter. At 12 days since release people were questioning whether we'd ever hit an exchange in this market, since that is a very long time compared to some coins being hyped with less substance. We ask now that you consider the amount of work we've put into the community, forward planning, giveaways and dealing with each and every concern personally. We also ask you consider our unique approach and in some ways the new 'standard' we've set for 2014. While obviously we weren't the first, we have helped force new alt-coins wanting to be taken at least semi-seriously to now address public ledgers, transparency, long-term planning, a little substance and a more dedicated development team. This is a powerful stepping stone in letting us more pro-actively approach merchants and charities. The effort and work going into this is not going to end now.
