According to professional traders, long-term investing is best when a coin has strong fundamentals, a real use case, a trusted team, and a solid ecosystem, which is why top market-cap coins like Bitcoin and Ethereum are often accumulated during market crashes or panic phases and held for 1–3 years or more. Short-term trading is suitable when the market shows high volume, clear trends, breakouts, or news-driven momentum, and it requires proper technical analysis, strict stop-losses, and strong discipline. For beginners, long-term investing is generally safer, while short-term trading demands skill and experience; therefore, a professional approach is to allocate most capital to long-term investments, a smaller portion to short-term trades, and always invest only what you can afford to lose.
