TechFlow News, May 20: According to a Cointelegraph report, Bitcoin has declined approximately 40% from its all-time high in October 2025; however, long-term valuation models indicate significant upside potential remains. Based on the “Bitcoin Decay Channel” measurement of long-term trends, Bitcoin’s conservative year-end price range has been revised upward to $90,000–$255,000, with the high-end scenario reaching as much as $255,000.
This model fits a logarithmic decay trend to historical cycle highs and lows, showing that BTC approached the upper channel boundary at the peaks of the 2013, 2017, and 2021 cycles, while bear market bottoms fell near the lower boundary. Analyst Sminston stated that Bitcoin remains within a historic, long-term ascending channel and noted that the price range for 2027 could further expand to $128,000–$308,000.
