Market snapshot (April 28, 2026): Crypto markets are showing signs of accumulation in North America, coordinated recovery efforts in DeFi after a major exploit, and a tightening regulatory backdrop across the U.S. and Canada. BitMine keeps buying ETH even as paper losses widen BitMine Immersion Technologies continued to build its Ethereum position despite growing unrealized losses tied to volatility. The firm bought 101,901 ETH last week, lifting total holdings to about 5.08 million ETH. A week earlier it purchased 101,627 ETH, its largest weekly increase since December 2025. The balance sheet reflects the drawdown: BitMine's combined crypto and cash reserves are roughly $13.3 billion versus total investments of about $17.6 billion, implying unrealized losses above $6.5 billion. The Tom Lee-backed company has also staked nearly 3.7 million ETH, generating recurring yield from network validation to help cushion downturns and support cash flow. DeFi United lines up 30,000 ETH after rsETH bridge breach DeFi participants are moving to shore up rsETH following a major security incident. On April 18, a bridge operated by Kelp DAO was breached, leading to losses of around 116,500 rsETH valued at roughly $290 million. In response, Consensys and Ethereum cofounder Joe Lubin joined to form DeFi United, which has committed up to 30,000 ETH to support recovery and restore confidence. The plan, announced April 23, brings together participants linked to the Aave DAO, alongside contributors including Lido, Ethena, EtherFi, Frax, and Mantle. The effort aims to stabilize liquidity and rebuild rsETH backing, with governance votes across multiple protocols still in progress. Sharplink, a custody firm focused on Ethereum listings, is advising on recovery design and coordination. Tennessee signs law banning crypto ATMs and kiosks Tennessee Governor Bill Lee signed House Bill 2505, banning cryptocurrency ATMs and kiosks starting July 1, 2026. Installing these machines will be treated as a Class A misdemeanor, punishable by up to 11 months and 29 days in jail and fines up to $2,500. The move affects more than 570 self-service terminals in the state, including units run by CoinFlip and Bitcoin Depot. Lawmakers cited fraud prevention, with House Speaker Cameron Sexton saying the machines are increasingly used to target vulnerable groups, particularly older residents. Similar steps have surfaced elsewhere, including local bans in Massachusetts and proposed statewide limits in Minnesota. Canada advances bill to bar crypto political donations Canada is also tightening rules at the intersection of crypto and politics. Bill C25, introduced March 26, 2026, has passed second reading in the House of Commons, signaling early support. The proposal would ban political parties and candidates from accepting cryptocurrency donations, citing traceability concerns and enforcement challenges in campaign finance. Lawmakers framed the measure as part of broader efforts to strengthen election integrity, improve transparency, and reduce foreign-influence risk. The bill now heads to committee review for detailed scrutiny and potential amendments; no timetable has been set for that stage.
