If the pie falls to the range of 4.8-4.9, the 50% of the mainstream positions that were sold out will be replenished by two layers one by one, and the remaining three layers will be used to defend against a sudden drop to 4.4. If it falls below 4.4, the bulls will be able to stabilize their positions in the later period and then add them directly. The market does not support a deep decline, Ether upgraded in March, and the pie was halved in April #BTC
