Addresses in profit
addresses worth more than they cost
How many addresses are holding coins worth more than they paid. Counting addresses gives a tiny balance the same weight as a huge one, so this answers "how many holders are up" where supply in profit answers "how much money is up".
DefinitionAddresses whose average acquisition price is below the current price. Cost basis is specific identification, not average: a spend removes the exact cost of the exact output spent, so an emptied address returns to a cost basis of exactly zero. Read off the same 1,024-bin cost axis tier B uses for supply in profit.
LimitAn address is not a person and not a wallet. One person routinely holds thousands of addresses, one address can hold many people's coins, and ordinary wallet software makes a brand-new change address on almost every spend. So this line moves with wallet behaviour, change outputs, batching and consolidation at least as much as it moves with how many people own bitcoin. Read its direction and its shape; never read the level as a headcount. It is priced off the same series as tier B, so before 2012 it inherits thin, wide-spread quotes from a handful of exchanges, and coins created before height 68,774 have no price at all and carry a cost basis of zero. Addresses built only from pre-2010-07-17 coins carry a zero cost basis and are therefore always counted in profit; `addr_noprice` sizes that group.
