According to @AltcoinDaily, Bitcoin (BTC) is up roughly 100 percent over the past year as of Oct 3, 2025 (source: @AltcoinDaily post on X). Traders can verify the one-year change by comparing BTC-USD closing prices from Oct 3, 2024 to Oct 3, 2025 on Yahoo Finance and TradingView, which show a similar year-over-year doubling over that window (source: Yahoo Finance BTC-USD; TradingView BTCUSD Index). For trade setup, the prior cycle all-time high near 73,800 is the critical resistance; a sustained weekly close above that level points to trend continuation, while repeated rejection implies a range-bound market with mean-reversion risk (source: Coinbase BTCUSD historical ATH on Mar 14, 2024; TradingView BTCUSD chart). To gauge demand, monitor U.S. spot Bitcoin ETF daily creations and redemptions published by issuers such as iShares IBIT and third-party dashboards, which provide timely flow data for confirmation (source: iShares Bitcoin Trust daily flow reports; Farside Investors spot Bitcoin ETF flow tracker).
