Bitcoin (BTC) is seeing a renewed bout of exchange inflows even as trading activity has sharply rotated toward the U.S. session, a combination that traders often watch for clues on near-term market intent and liquidity conditions. Data from CoinGlass showed that as of May 18 at 01:27 UTC, major centralized exchanges held a combined 2,455,173 BTC.
The US securities regulator approved 21Shares' Hyperliquid ETF last week, adding to a growing number of cryptocurrencies converted into ETF wrappers in the US.
Institutional Bitcoin (BTC) holdings have climbed to an estimated 4.16479 million BTC, underscoring how quickly 'long-term holders'—from listed companies to ETF issuers and governments—are absorbing a meaningful share of circulating supply. According to data compiled by BitcoinTreasuries as of May 18 (UTC), 345 institutions collectively hold 4,164,790 BTC.
