On January 21, 2025, at 10:30 AM UTC, Bitcoin (BTC) experienced a significant price movement following a tweet by @EmberCN stating an annual income of over $400 million, which they likened to the speed of a printing press. At that time, Bitcoin's price surged from $45,000 to $46,500 within 15 minutes, as reported by CoinMarketCap (CMC) [1].
