Missing out on a market cycle can sometimes be really disappointing. But if you can follow the right approach and understand the rhythm, the profit opportunities across the entire cycle are within reach. Buying in at this position and waiting until before or after the Spring Festival, the feeling of profits being secured will be very different. The performance of these mainstream coins is worth close attention. The Federal Reserve's policy changes are reshaping market expectations; whoever catches this wave's rhythm will gain the upper hand.
