Unit 1 · Level 3 · Exchange & stablecoin flows
The long goodbye
One of the most famous on-chain charts: bitcoin held on exchanges has been in a multi-year decline, from roughly 17% of supply in early 2020 to under 12% by 2024. The classic reading: coins on an exchange are one click from being sold, so coins leaving suggests holders plan to keep them. The trend is real, but like every metric in this league, the honest version comes with footnotes.

What you get asked
Why do analysts watch how many coins sit on exchanges?
An exchange balance is coins sitting in the shop window: ready to trade. Fewer coins there means less supply parked next to the sell button. That's the whole intuition.
The classic reading of falling exchange balances: holders are moving coins to self-custody because they intend to ___ them.
Withdrawing to your own wallet adds friction to selling: you'd have to deposit again first. That friction is read as intent to hold.
Match each exchange-balance move to its textbook interpretation
Direction, size and breadth all matter. A move across many exchanges is a crowd signal; a move at one venue is often just plumbing.
What's the honest caveat on the 'coins leaving exchanges = bullish hodling' story?
Since spot bitcoin ETFs launched in 2024, huge sums moved into custodian wallets. Same chart shape, very different story: 'off exchange' is not one single behaviour.
How should a careful analyst treat the multi-year decline in exchange balances?
Less coin on exchanges is interesting supply context, but supply is only half a market. Demand still decides the price, and this chart says nothing about demand. 🐜
