Supply aged 7 to 10 years

Bitcoin bought before most people had heard of it. This band grows almost monotonically, which is itself the finding: these coins essentially do not come back.

DefinitionCirculating supply held in unspent outputs whose age falls between seven and ten years. Age is real elapsed time off a monotonised block clock (the running maximum of block timestamps), not blocks divided by 144. The twelve bands sum to circulating supply exactly, verified to machine precision.

LimitA rising band here is mostly coins ageing in from below, not new conviction. Age is per output, not per owner: consolidating coins or receiving change resets the clock on bitcoin nobody sold.
