Bitcoin Slides With Rising Yen Costs as Carry Trade Tension Builds
Global crypto markets faced renewed turbulence as Bitmex co-founder and Maelstrom CIO Arthur Hayes explained on social media platform X on Dec. 1 his assessment of why bitcoin had dropped below $85K.
He explained that bitcoin dumped because traders believed the Bank of Japan (BOJ) had shifted a potential December rate hike into focus, and that a USD/JPY move into the 155–160 area signaled a more hawkish stance from policymakers. As of writing, BTC is trading at $84,966.
