BlockBeats News, March 19th, according to Coinglass data, Bitcoin's volatility has recently remained high, reaching 3.48% in the past three days, hitting a new high since September 2024, reflecting to some extent the market's lack of liquidity. The Federal Reserve will announce its interest rate decision tonight (2:00 AM Beijing Time on March 20th), and it is expected that the volatility will surge at that time.
