Bitcoin hits a new high, while other altcoins plummet. If nothing unexpected happens, there is a high probability that some major event that affects the market will break out, and it is a black swan event with bad results. The main force sells altcoins for risk aversion. The bull market is clear, but the main force will use all means to wash you out of the car. The best operation is to buy when the price drops. The medium operation is to buy and hold the currency. The worst operation is to chase the rise and kill the fall. Then please leave after buying.
