This page projects the Bitcoin price over seven horizons — 3 days, 1 week, 1 month, 3 months, 6 months, 1 year and 3 years — with daily, weekly and monthly views. It shows two complementary things: a conservative statistical forecast, and a historical scenario table replaying every comparable window BTC has actually lived through, which can fall over six months yet rise over a year. Every number is computed in your browser from BTC's public Binance daily closing prices; nothing is stored and no account is needed.
The forecast splits BTC's trend into two parts: a market component (its beta to Bitcoin) and a coin-specific component(alpha), each shrunk toward zero as a Bayesian posterior mean. The market drift is extrapolated assertively, so a coin's long-run trend does reach the forecast. That is a choice, and it has a measured cost: forecasting one year ahead across 24 coins, this setting is about 2.6% worse in RMSE than simply assuming the price does not change, and on a pure random walk it can manufacture a 3-year move of 34.6% from noise alone. Coins with under two years of history fall back to a conservative prior, and the drift is capped, to limit that. We do not tilt the forecast with technical indicators. Backtested across 46 coins with non-overlapping forward windows and a coin-level t-test, a consensus of trend (SMA 20/50), Bollinger %B, RSI(14) and an ATR trend measure had a 5-day directional accuracy of49.8% — a coin flip. Momentum and reversal were no better: their signs flipped between pooled and per-coin fits.
Two consequences are worth stating plainly. The forecast extrapolates a trend that is not statistically significant, so treat it as one scenario rather than a validated prediction, and read the range and probabilities beside it. And the daily forecast line is smooth and monotone: we tested a day-of-week effect to see whether a zig-zagging daily forecast could be justified, and on the market series no weekday reaches statistical significance. Direction is not forecastable, but volatility is, so each horizon uses its own measured blend of BTC's current and long-run volatility. The range and the probability of a given move therefore carry at least as much information as the number itself.
