Revolut data breach exposes Bitcoin transaction records as altcoins slide broadly

The day's dominant story was a data breach at Revolut, the UK-based fintech with a large crypto user base. The company disclosed that a fraudulent request spoofing a government domain tricked it into handing over customer passport data and Bitcoin transaction histories. That combination — personal identity records tied to specific Bitcoin activity — is the kind of exposure that makes regulators and users uncomfortable in equal measure. It didn't cause a market crash, but it added a layer of unease to an already soft session. Bitcoin's -0.84% slip kept it well below $81,700, the resistance level that on-chain analytics firm CryptoQuant identified this week as the threshold Bitcoin needs to clear before a sustained bull market can be confirmed. Until that level breaks, the market is in a holding pattern — and Sunday's session did nothing to change that picture. Altcoins bore the brunt of the selling. BNB fell 2.88%, Ethereum and Solana each dropped 2.25%, and XRP slid 2.17%. Zcash took the steepest hit at -5.41%, with the Revolut breach plausibly amplifying existing regulatory anxiety around privacy-focused coins — assets that already draw scrutiny for their ability to obscure transaction trails. Monero, the other major privacy coin in the top 15, bucked the trend with a +1.08% gain, though no specific catalyst explained the divergence. TRON was the only other asset to hold flat, essentially unchanged at +0.01%.

• –Revolut disclosed that customer passport data and Bitcoin transaction histories were leaked after a fraudulent request successfully impersonated a government domain — a reminder that crypto data held by fintech platforms carries regulatory and personal risk beyond the blockchain itself.
• –Crypto billionaires Ben Delo and Christopher Harborne donated a combined $97 million to Nigel Farage's Reform UK party, one of the largest political donations in UK history and a signal of growing crypto-industry involvement in mainstream electoral politics.
• –Ripple's stablecoin division outlined a $13 trillion addressable market for its RLUSD stablecoin as a corporate treasury instrument, a significant narrative push even as XRP fell 2.17% on the day.
• –Bitcoin Suisse announced plans to cut up to half its Swiss workforce, shifting operations abroad — a sign of continued margin pressure across crypto service and custody firms.
