BTCPay Server Links Hot Wallet Thefts to Older Versions as Bitcoin Slips to $76,543

Security is the main theme on Tuesday. BTCPay Server, the open-source bitcoin payment processor, has linked hot wallet thefts to instances running version 2.4.1 or earlier. It first told operators to shut their servers down, then urged them to upgrade to version 2.4.7. The size of the losses and the method of attack have not been disclosed.

The news arrives during a soft patch for digital assets. The largest tokens fell over the past day and week, and a widely followed sentiment gauge points to fear.

Markets at a glance

Bitcoin traded at $76,543 this morning, down 2.2% over 24 hours and 3.6% over seven days. Ether was at $2,245, down 1.9% on the day and 2.5% on the week, slightly smaller losses than bitcoin's.

BNB fell 2.2% to $694.3 over the past day. Its 5.7% decline over seven days is the steepest weekly move among the large tokens tracked here. XRP was close to flat on the day, down 0.4% at $1.25, but is 3.5% lower over the week.

The two largest stablecoins, Tether and USDC, held at $1. The Crypto Fear & Greed Index stands at 26, in "Fear" territory. That reading is consistent with the broad but measured selling across the major assets.

The stories that mattered

BTCPay Server links hot wallet thefts to instances running version 2.4.1 or earlier. The project's guidance changed from an initial instruction to shut down servers to a call to upgrade to version 2.4.7. BTCPay Server is self-hosted, so the response depends on individual operators acting. With losses and the attack method still undisclosed, the full extent of the damage is unclear.

Ethena Pay launches Earn+ rewards product built on Aave V4 lending on Avalanche. Users must opt in to the product. It routes balances into a Steakhouse-curated Upshift vault that supplies USDe and borrows USDT. Withdrawals are processed within 24 hours rather than instantly. The structure layers several protocols and curators on top of a payments product, a design that is becoming more common in stablecoin yield.

Musk mocks Altman's argument that DRAM is better used in AI data centres than home PCs. The OpenAI chief executive argued that memory sitting idle in personal computers is a poor use of scarce supply. Elon Musk replied with a film meme, reopening the long-running feud between the two. Beneath the exchange lies a real question: how a constrained supply of memory is shared between consumer devices and AI infrastructure.

What to watch

• Whether BTCPay Server discloses the scale of the hot wallet losses and how the attack worked, and how quickly operators move to version 2.4.7.
• Take-up of Ethena Pay's Earn+, and how users respond to the 24-hour withdrawal window and the product's reliance on Aave V4 and a curated vault.
• Further public argument over how scarce DRAM supply should be divided between AI data centres and personal computers.
• Whether sentiment recovers from its current "Fear" reading of 26 as bitcoin and ether extend their weekly declines.
