In this circle of the secondary market, there are two approaches: long-term holding and short-term speculation. Before buying, I think one should be clear about whether it is long-term holding or speculation. Correspondingly, one needs to consider the holding period, maximum position, and exit conditions.
The most important aspect of long-term holding should be selecting coins, estimating which will outperform Bitcoin in the future and beat over 80% of altcoins. If one believes that the certainty of this coin is good, one can adopt a dollar-cost averaging strategy, and even if the price is bought high, there is not much to worry about, because my thinking is based on averaging the price. According to individual risk preferences, a maximum position or pause and exit conditions should be set, then leave it to time to allow the market to test your judgment.
The most important aspect of short-term speculation should be the exit, as exiting is more difficult. Exiting from long-term holdings is relatively easier compared to speculative targets because there is more capital support. Speculative targets have lower certainty, are influenced by various market factors, and change quickly. Once a trend reversal occurs, the exit requirements for individuals become higher.
Of course, the choice between long-term holdings and speculative targets entirely depends on each person's market perception. Everyone has different views, but when buying a coin, one must clearly distinguish whether it is for long-term or short-term.
