A long-time Solana wallet that staked 991,079 SOL in 2021 sold another 30,000 SOL on May 19 for about $2.56 million, lifting total recorded sales since 2025 to 965,274 SOL worth $137.66 million. The wallet still has 381,140 SOL staked, valued at roughly $32.4 million, leaving the market exposed to potential additional supply if those tokens are later unstaked and sold.

Bitcoin is approaching its next halving with fewer than 100,034 blocks remaining until block 1,050,000, with estimates placing the event around April 17–19, 2028. The block subsidy is set to drop from 3.125 BTC to 1.5625 BTC, a change that could further tighten mining margins. Strategy and Blackrock together hold more than 1.66 million BTC heading into the supply reduction.

Strategy has accumulated 843,738 BTC, compared with BlackRock's 817,138 BTC, leaving a gap of roughly 26,600 coins. In April 2026, Strategy surpassed BlackRock after buying 34,164 BTC for $2.54B in one week, and later added 24,869 BTC for $2.01B. JPMorgan projects Strategy's 2026 bitcoin buying could total $30 billion, keeping the 1 million BTC mark in focus.

An onchain wallet analysts have associated with a16z has accumulated 2.11 million HYPE tokens valued at about $90.87 million since April 14, including a $16.9 million buy on May 18. The same wallet has also staked roughly 1.3 million HYPE worth around $51 million, while HYPE-related ETF activity expanded with 21shares' THYP launch on May 12 and a Bitwise BHYP filing update dated April 10.

Blockchain investigator ZachXBT said on Monday that Bitget allowed market makers to run supply-control manipulation that harmed retail traders, citing RAVE, RIVER, SIREN, and LAB. He also pointed to onchain activity around LAB, including 10 newly created wallets withdrawing 100M LAB tokens ($480M, 32% of supply) from Bitget within 12 hours after a sharp price move.

On May 18, the Verus-Ethereum bridge was hit by a coordinated exploit that drained about $11.5 million. The attacker removed 103.6 tBTC, 1,625 ETH, and 147,000 USDC, then swapped the proceeds into roughly 5,402 ETH held at address 0x65Cb25F9. Blockaid said it flagged the incident live and linked the wallet’s initial 1 ETH funding to Tornado Cash.

PeckShield reported that cross-chain bridges suffered eight major exploit incidents in May 2026, with attackers draining a combined $328.6 million. The tally follows April 2026's spike in bridge-related losses, including the approximately $300 million KelpDAO incident on April 18 and Drift Protocol's $200 million-plus exploit days later. Data cited in the report also puts total 2026 hack losses beyond $750 million through mid-April, with May's events adding further losses such as the Verus-Ethereum bridge drain of about $11.5 million.

Bitcoin slipped under $77,000 on Monday, extending a four-day decline as crypto markets saw $657 million in liquidations over 24 hours. Long positions accounted for $584 million of that total, while BTC traded around $76,000–$76,500 at press time with the 50-day EMA at $76,716 in focus.

Abu Dhabi's Mubadala Investment Company increased its position in BlackRock's iShares Bitcoin ETF (IBIT) by 16% in Q1 2026, reporting 14.7 million shares worth $565.6 million. The disclosure shows the share count rose even as the reported dollar value slipped from Q4 2025 levels, which the report attributes to a pullback in bitcoin prices from late-2025 highs.
