In this circle, when engaging in the secondary market, there are two approaches: long-term holding and short-term speculation. Before buying, I think one should be clear about whether to hold long or to speculate, which corresponds to considering the holding period, maximum position, and exit conditions.
The most important thing for long-term holding is choosing the right coin, estimating that it will outperform Bitcoin in a future time period and beat over 80% of altcoins. If one believes the certainty of this coin is good, a dollar-cost averaging strategy can be adopted. Even if the price is bought high, there is not much to worry about because my approach is based on averaging the price. Depending on personal risk preference, a maximum position or conditions for pausing and exiting should be set, then let time test your judgment.
The most important thing for short-term speculation is the exit, because the difficulty of exiting is higher. Exiting long-term holdings is relatively easier than exiting speculative targets, as there is more capital support. Speculative targets have lower certainty and are influenced by various market factors, changing rapidly. Once a trend reversal occurs, the exit requirements for individuals become higher.
Of course, long-term holdings and speculative targets completely depend on each person's market understanding, and everyone has different views. However, when buying a coin, it is essential to clarify whether one is doing long-term or short-term.
