According to the source, Tom Lee stated that Bitcoin (BTC) will reach a new all-time high before the end of January 2026 (source: Tom Lee public forecast, Dec 1, 2025). If realized, this would require a breakout above BTC’s previous record set in March 2024, defining a clear resistance reference for traders (source: CoinMarketCap historical BTC price data). The specified timeline provides a trading window to monitor price action versus the prior ATH for breakout confirmation or rejection into early 2026 (source: Tom Lee forecast window; ATH level per CoinMarketCap).
