Doge has fulfiled its prophecy, nothing can take that away, ever, but I did drop a tear when I saw all the videos from the contest deleted
Nevertheless, it is always better to bring Dogecoin to more exchanges, such as such young exchanges:
Shardax(will be implemented and fully operated in third quarter this year; voting campaigns have been run).
Altex (available for now and has two trading pairs in BTC and LTC)
Sure it would be quite a good idea to have more exchanges. But you can´t always trust new ones and it is traded on a high number of reputable exchanges, might be enough
