There are three principles for altcoins: the market is stable, the sector is hot, and the leader is strong. Personally, I think there are two things to consider when it comes to altcoin speculation. The first is that the market share needs to be stable. The second is to grasp the main line. Altcoins are beginning to differentiate. Some coins with well-established platforms have a higher probability of rebounding, while weak coins will still fluctuate greatly. While remaining cautiously optimistic, we must prevent the risks caused by the big pie turning back. Therefore, operations should be focused on short-term positions and small positions.
