According to CoinMeta, a historically reliable Bitcoin trading rule indicates that a major buying signal is about to arrive. This trading rule is based on Bitcoin's four-year halving cycle and points to another potential buying opportunity. However, this time the pattern may not be as effective as before, as spot Bitcoin and institutional investors have a greater impact on the market than in the past. According to a 2023 report by Pantera Capital, the “500-day rule” suggests that investors who buy Bitcoin about 500 days before a halving and then sell about 500 days later have historically made a profit. This strategy has generated returns of up to 34 times in previous cycles. Nevertheless, market observers warn that current market conditions may undermine the effectiveness of this pattern.
