Right now there is no way to get btc out of bter.  If you sold high and can get more doge trade your btc -> doge then you can withdraw doge/xpm/ppc only ones I've tried lately to another exchange that with allows btc withdrawal.  Once you get your doge/xpm/ppc whatever to another exchange, trade that for btc.  Now you have btc at an exchange that lets you withdraw, send/sell it to coinbase or some other service that converts btc to USD fiat.
