Understanding this chart
Each bar averages every January, every February, and so on across Bitcoin's full history — the long-run seasonal fingerprint of the market.
Averages hide variance: a +10% average month can still lose money four years out of ten. Read this next to the Monthly Returns heatmap, which shows the spread behind each bar. Small-sample caveat applies — there are only ~15 observations per month.
