Change of the exchange reserve over the last 30 days, in BTC: reserve(today) - reserve(30 days ago).

Calculated by BGeometrics from our own Bitcoin full node, using a set of addresses labelled as belonging to exchanges. Inflow is the BTC received by those addresses during the day; outflow is the BTC spent from them.

Green bars mean exchanges hold fewer coins than a month ago (net withdrawals); red bars mean they hold more (net deposits). Long green stretches are typical of accumulation phases.

Address labelling never covers every exchange wallet, so absolute levels are an estimate; trends and large moves are more reliable than the exact figure.
