Transaction values sum all outputs, including change. Address labels and large amounts do not establish a purchase or sale. Pending coverage is sampled and may miss transactions.

How it works

Confirmed balances use funded minus spent outputs from a public Bitcoin explorer. Pending changes are separate. Each observation has its own check time; ≈ marks a rounded provider balance.

A Bitcoin address is not a complete wallet or an identified person. This page reports public observations, with their sources and times.
