BitMEX is at the forefront of innovation when it comes to launching the next hot Altcoin product. We launched the world's first Ether Futures contract, and also were the first exchange to launch a tradeable market on Zcash. In addition, we often launch ICO futures contracts right after the ICO such as Qtum Futures and Status Token Futures.
Leverage differs from product to product, so please visit each individual contract's series guide for contract specifications. The best part about all the Altcoin products is that you need not have the Altcoin to trade, you can trade them all just using Bitcoin!
