Then why would anyone be buying the opposite side of that trade? Someone has to buy the long side of the futures for there to be a short side. The people on the long side have to therefore buy in equal magnitude to the short side. So if $1billion short sides are sold then also $1billion long sides are sold. If the guys on the short side are market selling their bitcoins to win the bet then why aren't guys on the long side market buying bitcoins to win the bet? The people on the short side are actually at a disadvantage because they first need bitcoins to market sell bitcoins. The guys on the long side need only cash to buy up the bitcoins. Every article I read about bitcoin futures wants normies to believe futures will tame bitcoin and that institutions are using futures to crash the bitcoin market. Everyone on reddit constantly talks about the expiry dates of futures like its a guarantee that the market is going to crash so that the short sided futures guys will win their bet. So basically what I'm saying is anyone who did any research into futures trading of bitcoins would have come across information claiming that the only side to buy is the short side. Now you would have me believe that the people buying longs in equal magnitude to the shorts are total idiots who couldn't even be bothered to read for 2 seconds on the internet and see all the people talking about how the short side is always right and how the manipulation is always to the short side to win the bets and make billions of dollars and yet there still exists enough idiots who somehow are smart enough to know how to buy futures but too dumb to do 2 seconds of internet research who are willing to lose their money every single week like clockwork?
