HODL Waves — Supply by Coin Age

Splits all BTC supply by 'how long since each coin last moved' (100% stacked). HOW TO USE: YOUNG bands (warm/red, under 6 months) SWELLING = old coins waking up, long-term holders selling → TOP/euphoria warning; OLD bands (cool/blue, over 1 year) growing = more coins going dormant, accumulation → BOTTOM/bear signature. A holding-behavior gauge, slow-moving, read over long cycles.
