We need to monitor this weeks Fed H.4.1 release to confirm whether the JP MOF repo’d their TSY for $ then sold them to buy Yen. If Bessent can get the counterparty limit increased then the Fed can create money using MOF TSY as collateral. https://t.co/3itJC8Kb0G

Thank you to my partners, my BitMEX employees, and most importantly our clients. It was an amazing ride. We did something special together. And I'm so proud of what we created and that we will shutdown responsibly on our own terms. Fuck TradFi, Fuck the Banks, Fuck the man.
