Exchange Netflow
Exchange netflow is the difference between coins flowing into and out of exchanges over a given period, for a single exchange or for all tracked exchanges combined. A positive netflow means exchange balances grew; a negative one means they shrank.
How netflow is calculated
Netflow is simply inflow minus outflow. If 10,000 coins were deposited to exchanges in a day and 14,000 were withdrawn, the netflow is minus 4,000. Added up over time, netflows explain how the total amount of a coin held on exchanges changes.
Like its components, netflow relies on a data provider's list of known exchange addresses, so it is an estimate rather than an official number.
How it is commonly interpreted
Positive netflow, meaning more coins arriving than leaving, is often read as rising potential sell supply on exchanges. Negative netflow, more coins leaving than arriving, is often read as holders moving coins into custody or long-term storage.
For stablecoins the reading flips: positive stablecoin netflow means more dollars available on exchanges, which some analysts see as potential buying power.
An example
Say a coin shows a netflow of minus 3,000 per day for six weeks. Exchange balances are steadily falling. Analysts might describe this as a supply squeeze building. Then, in a single day, netflow swings to plus 25,000 after a large holder deposits coins. That spike would draw attention, but its meaning depends on what the holder does next.
Pitfalls when using netflow
Netflow hides detail. A netflow of zero can mean a quiet day or a day when huge inflows and outflows cancelled out. Looking at inflows and outflows separately often tells a fuller story.
It is also vulnerable to labelling errors. When an exchange moves funds to new addresses the provider has not yet identified, it can look like a massive outflow. And the growth of exchange-traded funds and other custodians means many coins now sit outside exchanges without being in anyone's personal wallet. Treat netflow as context, not as a timing signal.

Frequently asked questions
Is negative exchange netflow bullish?
It is commonly read that way, since fewer coins sit on exchanges ready to be sold. But it does not predict price, and labelling errors or custody changes can distort it.
What does positive netflow mean?
More coins were deposited to exchanges than withdrawn in the period. It can signal growing sell interest, but deposits also serve trading, collateral and other purposes.
Why can netflow be misleading?
It nets out two flows into one number and depends on accurate exchange address labels, both of which can hide what is really happening.
