A friend left me a message saying, "Bitcoin has rebounded strongly. If it continues to rebound and reaches 80000, there shouldn't be five waves of decline, right? Even if it falls, it won't fall below 60000, right We cannot just watch the price of Bitcoin rise and then say it's bullish, and forget the tragedy of being cut off when it rebounds. We cannot ignore the essence of market operation rules and the power of medium - to long-term trends just because of the surface phenomenon of short-term price fluctuations. Even if the price of Bitcoin rebounds to around 80000 in the future, it will only be a dead cat rebound in the fourth wave, which is an excellent opportunity to enter the market and lay out mid line short positions. The main downward trend in the fifth wave will only be delayed but not absent. I still firmly believe that Bitcoin is currently only in the middle to late stage of a bear market, with even deeper and greater drops still to come. We are highly likely to see Bitcoin priced around $45000 in the second half of the year.
