When was created the first bitcoin exchange with derivatives?

I have a friend who is crazy about an idea which I believe is wrong. He thinks that the first bitcoin derivatives showed up in 2017, this is why he are having a bear market since.

This is false, but I couldn't find anything to support this idea and show him.

Does anyone have a link or something showing which was the first cryptocurrency exchange with derivatives?


Edit: I made a small research and found something:

As early as 2011, entrepreneurs were interested in building marketplaces (which were very basic websites run by a handful of individuals) to trade bitcoin derivatives such as ICBIT. Traders could engage in arbitrage to buy the digital currency at spot and sell futures contracts if a premium existed (receiving their profits in BTC). Futures also enabled traders to hedge price volatility and lock-in a price for their BTC.

Not sure about the first, but Bitmex is said to be around since 2014 according to this[1]. But shouldn't he prove his point first? Did he have data which exchange is the first one?

Well, it is a conversation. I like to talk to close friends about bitcoin, and people come up with very crazy arguments about the reasons not to buy... This is one of them... BUt it is wrong, ofc. Thanks for the info.
