One of China’s “Big 3” digital currency exchanges has removed trading fees—temporarily—on U.S. dollar-based bitcoin trades.

BTCC announced that effective March 1, the “BTCC USD Exchange will temporarily remove all trading fees, meaning 0% fees for both maker and taker orders. This promotion will continue until March 31st, 2017.”

The promotion, however, applies only to the company’s international exchange site. Fees will remain in place at the company’s Chinese exchange platform, BTCChina.com.

Tendai Musakwa, a representative for the digital currency exchange, told CoinDesk that the surprise promotion was a “tactical move” to outmaneuver rivals by focusing on the company’s international reach.
