Bitcoin experienced a significant decline on December 1st, dropping nearly 7% to fall below $84,000. This downturn was mirrored by Ethereum and Solana, which fell by 7% and 8%, respectively. The sell-off was attributed to the unwinding of the yen carry trade following the Bank of Japan's indication of a potential rate hike, alongside stalled inflows into Bitcoin ETFs. In response to market conditions, Strategy, a major Bitcoin holder, announced a $1.4 billion reserve to meet future obligations. Despite this move, the market sentiment remained bearish, with Strategy's stock price declining by 7.9%.
