Buffett is about to retire. What words of wisdom before retirement are worth rethinking? Everyone knows that the old man has always insisted on value investing. For the crypto community, it is difficult for us to know who the future value stars will be, and which coins will break through and thrive (although it is currently $BTC ). The principle we can learn and adopt is to wait; opportunities come from waiting, not in a day, a week, or even a month. We actually know that no matter how advanced a genius is, frequent trading ultimately leads to liquidation. If we cannot let go of small fluctuations, what we lose is our capital. Therefore, before trading, we must set a trading principle for ourselves, determining what time frame we are trading in, rather than being swayed by rumors. I personally prefer at least a 4-hour time frame; the reliability of daily and weekly charts is better. The role of shorter time frames is to provide more precise entry timing within larger cycles, rather than making entry signals based solely on short time frames. More extreme trading principles, like Buffett's, involve waiting for a major panic in financial markets, presenting a clear oversold condition (for instance, during the COVID-19 period, some companies' annual stock dividends even exceeded the principal of holding the stock for a year), before trading and buying the dip, such as during the COVID-19 pandemic, financial crises, wars, and other factors. Learning from this, we don't necessarily have to wait for this moment entirely, but when it arises, I hope everyone does not hesitate!
