Bitcoin traded near the lowest levels since September after an earlier swoon extended its weeks-long decline from an all-time high to about 40%.
The largest cryptocurrency by market value fell as much as 4.9% to $41,008 before stemming the decline during U.S. trading hours. It hit a record of almost $69,000 on Nov. 10. Ether, the second-largest, dropped as much as 9% to its lowest level since Sept. 30. Both of those tokens, as well as others including Binance Coin, Solana, Cardano and XRP are down more than 10% in the past seven days, according to CoinGecko.
