帮主郑重：比特币跌破8.7万！四年周期+去杠杆，中长线该抄底还是观望？

Group 1 - Bitcoin has fallen below $87,000 for the first time since April, with a single-day drop exceeding 4%, marking a decline that has persisted for over a month due to whale sell-offs and a lack of buying interest [1][3] - The market experienced a significant downturn after a record rise in October, leading to short-term traders continuously liquidating positions, which has resulted in increased selling pressure [3] - Two key factors driving the current decline are identified: the self-fulfilling nature of the "four-year cycle," where whales have sold over $20 billion in assets since September, and the ongoing deleveraging in the market, which has diminished the buying momentum that previously supported Bitcoin's rise [3] Group 2 - The volatility of cryptocurrencies is highlighted, advising against impulsive trading based on short-term emotions; investors are encouraged to reassess their long-term value outlook before making decisions [4] - It is recommended that potential investors wait for reduced volatility and stable support levels before entering the market, as the deleveraging process is not yet complete [4] - Emphasis is placed on managing position sizes due to the inherent risks associated with cryptocurrency investments, advocating for a steady approach rather than speculative betting [4]
