Bitcoin treasury firm Nakamoto has transferred 1,003 BTC to Cobo as collateral for a previous $250 million convertible bond financing. This marks the second additional BTC collateral transfer by Nakamoto this week, as reported by analyst Emmett Gallic using Arkham monitoring data. The initial offering price for the bond was set at Bitcoin's all-time high of $124,000. However, with the current market downturn, Nakamoto faces significant margin pressure, highlighting the risks associated with excessive leverage in the cryptocurrency market.
