Bitcoin exchange supply lowest since 2018

Santiment data published on May 15 showed 5.6% of bitcoin’s supply sitting on exchanges, the lowest share since 2018, according to the analytics firm’s weekly market summary. The same update put Ethereum’s exchange supply at 4.6% and listed $187.65 million in token unlocks for that day. The bitcoin figure then spread through crypto social-media posts and market threads in the following days, including reposts on May 19. ### Why are traders focused on one exchange-supply number? The 5.6% reading matters because it tracks how much bitcoin is held in wallets associated with centralized exchanges, where coins are typically easier to sell. Santiment says its “Supply on Exchanges” metric measures the amount of BTC held in exchange wallets and that a decline can indicate coins are moving into private wallets rather than staying on trading venues. (app.santiment.net) Finbold, citing Santiment data, reported that the decline left bitcoin exchange balances at an eight-year low. Coindoo, also citing Santiment, reported the more precise reading at 5.623% and said the level was the lowest since 2018. ### Does a lower exchange balance mean bitcoin is about to rise? Santiment’s own description is narrower than that. The firm says lower exchange balances can reflect a more bullish market structure because fewer coins are immediately available for sale, but the metric does not by itself predict the timing of a price move. (app.santiment.net) Santiment’s broader weekly note for mid-May also struck a more cautious tone. (finbold.com) In that report, the firm said late-May conditions showed “a mismatch between euphoric sentiment and incomplete on-chain confirmation,” while bitcoin was testing roughly $81,000. That means the exchange-supply reading was one supportive data point, not a standalone trading signal. (app.santiment.net) ### What did the same Santiment update say about Ethereum? Ethereum’s exchange supply was 4.6% in the same May 15 dataset, according to the reposted Santiment figures. Coindoo, citing Santiment, reported a 4.575% reading and said that was still near historically low levels even though ETH exchange supply had risen from about 4.2% ten days earlier. That contrast is part of why the bitcoin chart drew more attention. (app.santiment.net) Bitcoin exchange balances were still falling to a multi-year low, while Ethereum’s reading appeared to be edging higher from a similarly compressed base, according to the Santiment-linked reports. ### Where do token unlocks fit into this picture? Santiment’s May 15 roundup also cited $187.65 million in token unlocks scheduled for that day. (coindoo.com) Token unlocks are separate from bitcoin exchange balances, but traders often track them alongside flow data because newly unlocked tokens can increase available supply in the market. A separate crypto-education article on unlock dynamics said low liquidity and unlock schedules can amplify price swings in digital assets. (coindoo.com) That does not mean the May 15 unlock figure directly affected bitcoin’s exchange balance, but it helps explain why the two metrics often travel together in market commentary. ### What should readers watch next? Santiment’s chart pages for bitcoin exchange supply remain the clearest place to watch whether the 5.6% area holds or reverses. (app.santiment.net) The firm’s weekly written summaries also provide context on whether wallet flows are being confirmed by sentiment, ETF demand and broader market activity. As of May 21, market trackers still showed bitcoin trading below the roughly $81,000 level discussed in Santiment’s mid-May note. (cryptoadventure.com) The next update to exchange-wallet balances, rather than the recycled May 15 snapshot alone, will show whether coins continue moving off exchanges. (app.santiment.net)
