i have dumped more than 50m doges around 0.32-0.50 BTC per megadoge... so yeah, i understand his pain
you can trade doges on cryptsy btw for bitcoins and sell bitcoin on bitstamp for the example...

they recently added doge/btc chart
btc-e works aswell they are OK but noone knows who are behind them, they say it for their own protection. but well, btc-e wallets have a LOT of BTC/LTC so i understand them...
i am really into crypto and i have a quite large scrypt farm (100+ MH/s :P) growing month by month if you need any help related to cryptos you can find me on freenode
for doges, is it better to hold for a now, since block halving comes around mid february, and price will propably go up...
