After we post this message, only one customer sell bitcoin to us:(

But we do need more bitcoin now, since many user get gift cerfiticate from our site, and they want nothing else but bitcoin, so our bitcoin is running out. We do hope those who want to sell trade with us. Remember, in our site, you can sell at a higher price. Besides, you may also win it back if you are wise enough to pass our exam. It's worth doing, don't you think so?
