A fundamental strategy for Bitcoin investment is to buy and hold. This approach is simple and straightforward: after purchasing BTC, patiently wait for the appropriate selling opportunity. During the waiting period, investors can use their time for personal development and enjoying life, rather than being overly focused on market fluctuations. This 'buy and hold' strategy is suitable for long-term investors as it reduces the stress and costs associated with frequent trading. However, investors still need to be cautious and closely follow market trends to make selling decisions at the right time. After all, the crypto assets market is highly volatile, and timely adjustments to the strategy are also important.
