Cryptoccino — Tuesday 27 October 2026

Brazil election shock crashes local markets. Lula da Silva’s upset win over Flávio Bolsonaro — whom prediction markets had at 80% — sent the iShares Brazil ETF down as much as 26% and pushed the dollar up 12% against the real. The result is the sharpest reminder yet that thin prediction market liquidity in regulated-out jurisdictions produces badly miscalibrated odds. decrypt decrypt

Grayscale positions Bitcoin as less volatile than a basket of large-cap stocks. A new Grayscale note argues Bitcoin’s realised volatility has fallen below that of Oracle, Coinbase, Honeywell and SanDisk, framing the asset as a portfolio stabiliser rather than a pure speculative punt. Short-term holder profitability also dropped to 70%, which Glassnode reads as a healthier entry zone. cryptobriefing cryptobriefing

Strive closes in on the second-largest corporate bitcoin treasury. Strive added roughly $511 million in bitcoin, putting it within 1,000 BTC of Metaplanet’s position, and simultaneously announced a $1 billion preferred stock offering programme to fund further purchases. StoneX lifted its price target 34% to $43, reiterating its Buy rating. theblock theblock

Bernstein cuts Coinbase target, raises Circle’s as product mix shifts. The broker sees prediction markets and derivatives taking share from spot trading revenue, which disproportionately benefits Circle’s fee model and pressures Coinbase’s take rate. Robinhood sits in the middle as its derivatives book grows. theblock

Ripple wins final OCC sign-off for its national trust bank. The approval lets Ripple place RLUSD reserve management and custody under federal supervision while keeping issuance at its existing New York-regulated entity. Aviva Investors also launched a tokenised share class of its £29 billion Sterling Liquidity Fund on the XRP Ledger on the same day, and XRP whale concentration hit its highest level since November 2022 at 68.5% of supply. theblock coindesk cryptobriefing theblock

BlackRock, SBI and Startale link tokenised MMFs to a yen stablecoin. The three parties signed an MOU to explore connecting BlackRock’s tokenised money market funds with SBI’s JPYSC yen-pegged stablecoin, a structure that could route institutional liquidity through on-chain settlement rails in Japan. It is exploratory for now but puts BlackRock’s tokenisation stack directly adjacent to a regulated domestic stablecoin. theblock cryptobriefing

Hyperliquid taps Kraken parent Payward as first CFTC-regulated HIP-3 deployer. The arrangement would make Payward the first CFTC-regulated entity to deploy on Hyperliquid’s HIP-3 standard, opening a pathway for regulated US perpetual futures products on-chain. The structure is still pending but signals the CFTC’s comfort with regulated intermediaries serving as the compliance layer for decentralised venues. theblock

Bitmine adds 10,452 ETH and runs its largest equity buyback. Tom Lee’s firm now holds close to 5% of circulating ETH supply but pivoted sharply toward share repurchases, buying back 2.04 million shares in what it describes as the largest equity buyback any crypto treasury company has executed. The simultaneous pivot to buybacks rather than further token accumulation is a tacit hedge against ETH’s recent underperformance. theblock decrypt coindesk

CoinDCX confirms $16 million loss from retired wallets, CEO had previously dismissed reports. India’s largest exchange says 15.99 million USDT was drained from wallets it decommissioned after last year’s $44 million hack, a process failure rather than a fresh external breach. Combined losses now sit near $60 million and the firm says it is absorbing the hit without customer impact. decrypt coindesk

Electrum wallet patched a confirmed exploit that rerouted funds to attacker addresses. Rogue servers could replace pending transactions, silently redirecting bitcoin to attacker-controlled addresses before users noticed. The flaw is patched in the latest release; users on older versions should update immediately. decrypt

CertiK flags $1.58 million wallet drain with funds routed through Tornado Cash. The attacker appears to have exploited poor key management practices before laundering proceeds through the mixer. No protocol name has been confirmed publicly yet. cryptobriefing

OCC pushes community banks to enter the stablecoin payments market under the GENIUS Act. Following finalisation of GENIUS Act implementation rules scheduled for January, the banking regulator is actively encouraging smaller institutions to issue payment stablecoins rather than ceding the space to fintechs. The framing positions stablecoin issuance as a defensive play for deposit franchises. coindesk cointelegraph_regulation

Canada opens 60-day consultation on stablecoin rules, bans yield. Ottawa’s draft framework requires one-to-one reserves, caps redemption fees at 1%, mandates fast redemption, and explicitly maintains the prohibition on paying holders interest. The consultation cites the US GENIUS Act as a reference point, signalling the framework is being calibrated for cross-border compatibility. coindesk cointelegraph_regulation decrypt

NBA becomes the third league to sign a CFTC prediction market MOU; NFL is still fighting in court. Following MLB and NHL, the NBA agreed to share information with the CFTC to protect game integrity as sports prediction markets migrate to regulated venues like Kalshi and Polymarket. The NFL’s continued litigation creates a two-tier league landscape for prediction market operators to navigate. theblock decrypt coindesk

South Korea edges toward a fourth delay on its crypto gains tax, this time to 2029. Lawmakers are reportedly pausing again to align with the US timeline for integrating the OECD’s CARF digital asset tax framework, which requires data-sharing with foreign regulators. A 2020 policy that has now been deferred four times is beginning to look structural rather than transitional. coindesk cointelegraph_regulation theblock
