Odaily News Arthur Hayes, co-founder of BitMEX, posted on X: "I have closed my BTC short position and made a profit of 3%, which is enough to pay for my food and bar bills. Yellen is watching the market and made a statement over the weekend that if market conditions continue next week, Bitcoin 'may' rise because the US dollar liquidity is expected to increase." Earlier on September 6, Arthur Hayes posted on the X platform that "Bitcoin is expected to fall below $50,000 this weekend, and shorting has been carried out."
