Bitcoin and Ethereum are experiencing a sharp pullback in trading momentum right now. Over the past day, BTC and ETH have both seen their trading volumes crater by roughly 70%—and the pain isn't confined to the majors. Top-tier altcoins are getting hit just as hard, posting similar volume declines across the board. It's the kind of action that often signals traders are stepping to the sidelines, either reassessing positions or waiting for clearer directional signals before committing fresh capital. Market depth appears thinner than usual, which could amplify moves once liquidity does return.
