Bitcoin Rainbow

Bitcoin Rainbow answers "where does BTC stand?" with a picture, not a verdict. It plots every daily bitcoin close since 2010 (blockchain.info) on a rainbow growth chart: a trend line fit to the whole history, with nine color bands around it. rainbow_today returns the live price (Coinbase spot), today's line value, the band the price sits in, and how far it sits from the line. rainbow_history counts the past: the highest band BTC ever reached and when, the first and last dates it sat in each band, and how many of all priced days it spent in each one — counts of past days, never odds. cycle_check reads five classic cycle measures that can be counted from the price history alone (the Pi Cycle moving averages, the Mayer Multiple, the 200-week average, the halving clock, and the Ahr999 index) and prints each one with its own number, side by side, with no blended score. simulate_dca replays a steady weekly amount ($1 to $100,000 a week, over 1, 3, or 5 years) on the real price history and reports what would have gone in and what it would be worth today; every result ends "That is the past. Not a promise." explain_bitcoin gives one short, plain-English explainer per topic: price, technical, fundamental, rainbow, or ways_to_buy (IBIT in a stock account, or an exchange app; facts only). The tools are strictly descriptive: they never say buy or sell, never predict a price, and never answer "should I buy" with a verdict. Band names are colors only. Five read-only tools. No account. No ads. The tools collect no data about you. The WEBSITE carries the author's educational case — why he thinks bitcoin stands higher in ten years, the crashes, the ways crypto could fail, and general sizing ranges labeled "This is learning, not financial advice." The tools return none of that voice: no stance, no sizing, no verdict. The split is deliberate, and it is disclosed here rather than hidden.
