That example is shorting actual bitcoin too. For futures you don’t even have to borrow the underlying asset at all. It’s 100% based on contracts, and settled in US dollars, meaning you don’t even have to deliver the actual asset at all at the end of the settlement period.
Yes, but what I was saying is in order to 'win' on your future, you'd have to influence the actual btc price, and in order to do that, you have to own large amounts of btc to do so, which is what I was thinking is why would someone dump millions into btc to affect the price just to get the cash from their futures, just play btc then, but as sinbad said, you can just borrow it, no need to put money into it
