On Sunday, leading cryptocurrencies experienced a decline following a massive billion-dollar Bitcoin sale that led to a flash crash. Bitcoin saw a 2.18% decrease, trading at $112,839.95. Ethereum dropped 1.34% to $4,715.63, XRP fell 1.84% to $2.99, Solana decreased by 1.05% to $203.80, and Dogecoin saw a 4.05% decline to $0.2278. The flash crash occurred when a whale liquidated 24,000 BTC valued at over $2.7 billion, causing Bitcoin to fall from $114,000 to $110,000 in minutes. This move led to the market losing over $562 million in the last 12 hours. The whale still holds 152,874 BTC across various addresses and continues to sell, contributing to the price drop.
