What is the net flow and what does it mean?

−3,000 BTC: fewer coins on exchanges. Net flow = in − out: 5,000 − 8,000 = −3,000 BTC. A minus means fewer coins on exchanges, fewer at hand to sell. One such day means little; a streak of days is what matters.

Possibly prepping a sale, needs confirmation. To sell, coins usually get moved to an exchange first, so a transfer like this hints at a possible sale. But it can be futures collateral or a reshuffle. Look for confirmation in price, funding and volume: one transfer is not a signal yet.

What helps you tell how much this matters?

Check the address labels, e.g. in Arkham: fund, exchange or market maker. A bare address tells you nothing, a label changes everything. If 0x91…0c is an exchange, the transfer looks like prep for a sale. If it is a fund's cold wallet, it is more likely going into storage. Arkham Intel labels addresses and shows their large trades, roughly from $50k.

The amount is inflated: you cannot sell that much at the last price. The dollar amount uses the last price. But $30M is 150 times the daily volume (30,000,000 / 200,000 = 150): trying to sell would crash the price long before the end. The real value of the transfer is far below the headline.

Whales and exchange flows

Lesson 7 of 12 in the course “Analytics”. Free, with animations and a quiz.

On-chain: everything is visible

You have already covered macro and leverage. Now let’s look inside the blockchain itself: a shared public ledger of every transfer. Every entry is visible to everyone: from where, to where, how much and when. There are no names, only addresses, long codes like 0x3a…. On-chain analytics reads this ledger and looks for whales: holders of very large amounts. One of their transfers can weigh as much as thousands of small ones.

Exchange, wallet, blockchain

Three words you need for everything that follows. Exchange: a service where people buy and sell coins; while coins sit there, the exchange holds them. Wallet: a place where only you hold the keys to your coins, so only you can send them. Blockchain: the shared ledger where every transfer is recorded. Cold wallet: a wallet with no internet connection, used to hold coins long term.

Flow map: to and from exchanges

To sell coins, people usually move them to an exchange first, because that is where selling happens. So a big transfer to an exchange reads as a possible sale (red on the map). A withdrawal from an exchange reads as a move into storage, for example a cold wallet (green). Makes sense, but it is a hint, not a verdict: someone is preparing a move, and which one still needs checking.

Net flow: the day’s total

Net flow: how many coins went into exchanges minus how many came out. Example: in one day 12,000 BTC went in and 15,000 BTC came out. Math: 12,000 − 15,000 = −3,000 BTC. A minus means exchanges now hold fewer coins, so fewer are ready to be sold. A plus means more. A single day can be random, so look at a series of days in a row.

Exchange balances: 30 days beat one

Besides flows, watch balances: how much BTC sits on big exchanges such as Coinbase, Binance, Bitfinex, Kraken and OKX, over 1, 7 and 30 days. Example: Coinbase −2.4% over 30 days, so it holds 2.4% less BTC. Coins leaving an exchange means fewer are at hand to sell. One day is noisy, 30 days is more honest. Flow maps, the biggest transfers and exchange balances are all freely available.

Whale Alert and Whale Bot Alerts

An alert is an automatic message about an event. Whale Alert sends Telegram alerts about large transfers: coin, amount, from where and to where. Whale Bot Alerts does the same on X. In every alert check three things: size, direction (to an exchange, from an exchange or wallet to wallet) and whether it repeats several times in a row. Example from the picture: 1,500 BTC from an unknown wallet to an exchange.

Arkham and CryptoQuant: who is it

A bare address tells you nothing. Arkham Intel labels addresses: fund, market maker (a firm that constantly places buy and sell orders) or a known person. It also shows their large trades, from about $50k. CryptoQuant shows exchange flows and data on miners, the people who mine new BTC. If miners send noticeably more BTC to exchanges, selling pressure may grow.

Common mistakes

A big transfer to an exchange is not always a sale. It can be collateral for futures (leveraged bets on price) or a shuffle between the exchange's own wallets. Another trap: with an illiquid token that few people trade, the dollar amount can be inflated. It is calculated at the last price, but you cannot sell that much at that price. Good services warn about this right next to the amount.

How to check the signal

A flow is a hint; look for confirmation in three places. Price: does it fall after coins flow into exchanges? Funding: a fee between longs (bets on a rise) and shorts (bets on a fall) on perpetual futures. A strong plus means longs pay shorts and the crowd is overheated. Volume: how much was traded in total over the period. Bottom line: one transfer is not a signal, three things lining up make a picture.

What is the net flow and what does it mean?
Correct answer: −3,000 BTC: fewer coins on exchanges. Net flow = in − out: 5,000 − 8,000 = −3,000 BTC. A minus means fewer coins on exchanges, fewer at hand to sell. One such day means little; a streak of days is what matters.
How do you read it?
