Math alert:<p><i>... BTC China has facilitated approximately 340K XBT / ¥1.25B in trades. At the officially-stated 0.3% fee for buyers and sellers, that’s approximately ¥3.75M ($615K)...</i><p>There is a buyer and a seller for each trade so it should be 0.3% * 2 * ¥1.25B which is ¥7.5M. So they made twice as much as the article claims which is good for them but the 1st derivative of revenue curve is pretty steadily decreasing which is bad for them.<p>edit: Just thought about this a little bit more. This means there is a 60bps fee to go from an actual currency to bitcoin and vice versa. When you use bitcoin as a payment mechanism the buyer converts his currency to bitcoin, payment happens, then the seller converts bitcoins back to actual currency. So the exchange pockets 120 bps on every transaction where bitcoin is used exclusively as a payment technology. That's approaching Visa / Mastercard levels of transaction fees... not a bad business.
That's great for BTC China, but this new found revenue stream may be short-lived unless the owner (Bobby Lee) can find other ways allow for RMB deposits to go through as they were effectively shut off almost a week ago according to guidance from the Chinese central bank (aka. PBOC)[1].<p>[1] <a href="http://www.coindesk.com/bitcoin-price-falls-btc-china-exchange-shuts-fiat-deposits/" rel="nofollow">http://www.coindesk.com/bitcoin-price-falls-btc-china-exchan...</a>
