Bitcoin margin-trading platform BTC.sx back online

As the situation at Mt.Gox was unraveling last month, bitcoin derivatives platform BTC.sx decided to immediately halt all operations. The company promised to resume operations once agreements with other exchanges could be established.

After nearly three weeks of silence, BTC.sx quietly resumed operations yesterday. According to a report on CoinDesk, BTC.sx is currently partnering with Bitstamp, and looking at additional agreements with Coinsetter, BitFinex, ItBit and BTC-e.

The company’s website published a short note thanking customers for their patience.

Thank you for your continued support of BTC.SX, we are excited to inform you that our trading engine is back online. We thank you for your patience over this time while we’ve been busy integrating with new exchanges. We look forward to accepting new trades and we hope you’ll enjoy our improved service. We’ve also taken this opportunity to upgrade the performance of our platform.

It’s unclear what impact the temporary shutdown had on BTC.sx. At its height, BTC.sx was handling $40 million in brokered trades.
