Exchange Netflow Screensaver
The Exchange Netflow screensaver gauges the estimated net Bitcoin flow into or out of major exchange wallets, built from real, publicly attributed exchange address balances via mempool.space. It's free, runs in your browser, and ESC exits.
How the Exchange Netflow screensaver works
The saver polls a curated list of publicly attributed exchange wallet addresses via mempool.space, with no key required.
Balance changes between polls are summed into a live net inflow or outflow estimate.
A gauge leans toward inflow (often read as bearish) or outflow (often read as bullish) accordingly.
This is a real but partial estimate — see the FAQ for its limits.
A worked example
A run of real outflows nudges the gauge toward withdrawals — coins moving off exchanges, a pattern some traders watch as a signal, though it's only ever a partial picture.
Settings & tips
- Accent recolours the gauge.
- Publicly attributed addresses are a known subset — real exchange holdings are larger and partly unlisted.
- Treat the gauge as a directional signal, not an exact total.
Frequently asked questions
- Is this every exchange wallet?
- No — only publicly attributed addresses are trackable; real total exchange holdings are larger and partly unknown.
- Is a key needed?
- No. mempool.space's public API is free and key-less.
- Why do people watch this?
- Sustained outflows are sometimes read as holders moving to self-custody; sustained inflows sometimes precede selling — real correlations, not guarantees.
- Is it free?
- Yes — free, no download, in your browser.
