Bitcoin's recent surge above $80,000 has sparked optimism in the crypto market, yet a warning from crypto analyst Crypto Patel suggests caution. Patel highlights that Bitcoin has entered a historically perilous phase of its four-year cycle, which has previously led to significant downturns. Despite strong ETF inflows boosting Bitcoin's price, it remains 35.5% below its October 2025 peak. Crypto Patel's analysis on X points to a recurring pattern of mid-term year declines, with Bitcoin experiencing substantial drops in May during 2014, 2018, and 2022. Each of these years saw Bitcoin peak in May before suffering declines of 76.04%, 68.35%, and 70.06%, respectively. Patel warns that 2026, another mid-term year, could see a similar 66.54% drop, projecting a potential bottom between $50,000 and $30,000. Despite Bitcoin trading at $81,530 and nearing its 200-day EMA, Patel cautions that the current market optimism might be a "relief rally trap." He suggests that the bear market could persist through Q4, aligning with the four-year halving cycle, before a durable bottom is established.
