BTC 200-Week MA Heatmap: $79,676.63
Bitcoin's price coloured by how fast its 200-week average is climbing, with that average drawn underneath. The average has never fallen for long, and every past cycle bottom happened close to it.
The line underneath is the average closing price of the last 200 weeks — about four years. Each dot of the price **above** is coloured by how much that slow average grew over the previous 30 days: cold blue when it is barely moving, hot **red** when it is climbing fast.
Red dots mean the four-year average price is rising quickly; blue and purple dots mean it has nearly stopped rising. For example, a red dot means that four-year average grew more than about 15% in 30 days.
Bitcoin has closed **below** the line itself **only** rarely and in short stretches: 48 crossings since 2015 that group into just six clusters, every one of them inside a deep drawdown. It tells you where the market is, not where it goes next.
In words: average the last 1,400 daily closing prices (200 weeks), then colour each price dot by the percentage that average grew over the previous 30 days, on a fixed scale running from 0% to 18% per month.
Before mid-2014 there are not yet 1,400 days of price history, so the average uses every day available up to that point — without that, the hottest 2011 to 2014 era would simply be missing. Any growth **above** 18% a month is shown as the same **red**.
