Bitcoin opened at $63,497.25 and Ethereum at $1,883.15 on Monday, rebounding from weekend lows. However, both cryptocurrencies reversed course in early trading, with Bitcoin moving down to $62,643 and Ethereum to $1,840.70 as of 8:54 a.m. ET. This pullback occurs despite President Trump's announcement on Sunday that the U.S. paused planned airstrikes against Iran, which had been expected to provide some market relief.
