Derivatives are the next step in evolution of Cryptocurrencies as a bona-fide asset class. At Delta Exchange, it is our mission to accelerate this evolution and offer deep and liquid derivative markets to crypto investors across the globe. Bitcoin currently being the most prominent cryptocurrency will be at the vanguard of cryptocurrency derivatives. With this in mind, we at Delta Exchange have decided to launch with bitcoin futures. This will be followed by futures on prominent altcoins such as ether, ripple and stellar lumens. Once liquid crypto futures market are in place, we would look to launch trading of crypto options.

As things stand today, spot trading dominates crypto trading. And, with the exception of a few, most exchanges only support spot trading, i.e. investors can trade cryptos using other fiat currencies or other cryptos.
