What is really Bitcoin Derivatives ?
Are you asking because you don't know, or know but want to start a conversation?
Most people won't know what you're talking about if you ask about derivatives but if you ask about futures it will ring a bell.
In short, futures are a way for people who don't want to touch bitcoin for various reasons to speculate on its price. It's like cheat trading where you place a bet on the price of an assert without trading it. It's understandable when you're into very expensive things like real estate and want to speculate on the market but don't have enough money to own a property and also don't want to invest in shares of a company that does. With Bitcoin that is easy to buy, divisible, more or less anonymous, the reasons why someone would choose futures over the real thing are lame.
Is it the future of money? Bitcoin is, but betting on its price is not. How do you want to change anything and support this revolution if you're afraid to own bitcoin?
