The Friendly Market Options platform allows you to trade options on a number of cryptocurrencies. Options trading allows you to make significant profits (provided the trade goes the right way).
An option contract basically allows you to buy or sell at a specific price at a future date. So if the price goes up and you lock in a lower purchase price, you will make the difference on the underlying asset.
Options trading is necessary for any thriving economic ecosystem and it is a necessary feature for the advancement of the DeFi ecosystem on Casper.
