The BitMEX cryptocurrency derivatives exchange was launched in 2014 and currently averages daily trading volumes of US$3Bn. BitMEX built its matching and margining engine on kdb+ and cite the technology’s flexibility and speed in enabling them to pivot their product offerings twice: in the first instance from low-leverage inverse and quanto futures to high-leverage ones, and in the second case from high-leverage futures to its  flagship product, the XBTUSD Perpetual, which they proudly claim trades more than any crypto product in the world.
