BitMEX: new Bitcoin futures trading platform now in beta

BitMEX is a new Bitcoin futures trading platform from a group of DC founders that’s still in user-testing.
Cofounder Samuel Reed posted on the DC Tech Facebook group that he’s been working on it for the last year.
“Our beta is live with a futures trading simulation, and the first place winner gets 10 BTC (just over $5000),” wrote Reed. “This is a tech beta so anything goes; if you can hack our site and tamper with the results to put yourself in first place, you get the prize money.”
