China's bitcoin exchanges slap on trading fees

Being vigilant: The People's Bank of China launched spot checks on bitcoin exchanges BTCC, Huobi and OkCoin to look into a range of possible rule violations.

China's three largest bitcoin exchanges, whose activities have drawn increased scrutiny from the central bank, said they will begin charging trading fees effective Tuesday.

BTCC, Huobi and OkCoin said in separate statements on their websites late on Sunday that they will charge traders a flat fee of 0.2% per transaction.
