After the Federal Reserve's rate hike, Bitcoin once surged to the 80,000 mark; as of now, it is still holding near $81,000, with a slight 24-hour dip of about 0.2%. Ethereum is at $2,626, also experiencing a modest pullback. This round of rebound has been driven by short-covering, and the market is watching whether the traditional strong seasonality in the fourth quarter can continue.
