Ledger implant linked to $86M losses reignites ETF-vs-cold-wallet debate

Stack
- Ledger hardware implant losses could top $86M, per blockchain investigators
- Coldcard and Ledger both disclosed separate incidents within the same week
- Strategy added 250 BTC that week, lifting holdings to 848,250 BTC

Story
This isn't self-custody losing to ETFs. It's a supply-chain and phishing failure at one vendor, dressed up as a verdict on cold storage itself.

Watch
- Watch for Ledger/Coldcard to publish a revised threat model or attestation fix
- Watch for a second, unrelated vendor compromise confirming an industry-wide pattern

Sberbank gets state approval for crypto trading before December

Stack
- Russia's crypto exchange registry doubled from 4 to 10 operators in one week
- Digital custodians rose from 5 to 6, including both Sberbank and VTB
- USDT trades alongside BTC and ETH from Sberbank's December 1 launch

Story
Two sanctioned banks just got licensed custody and exchange status for dollar-pegged stablecoins. That's settlement infrastructure, not a trading app for retail customers.

Watch
- USDT volume share versus BTC/ETH after December 1 launch
- Any OFAC or Treasury statement naming Sberbank's crypto arm directly

USDC becomes the first dollar stablecoin under MiCA's toughest tier

Stack
- USDC: $73B market cap vs Tether's $184B, per Cointelegraph
- Only 45 tokens held "significant" status before USDC
- ECB's digital euro isn't expected before 2029

Story
This reads like a crackdown but EU issuers lobbied for it. Dollar stablecoins are becoming eurozone payment rails, and Circle just got the compliance stamp that makes that official.

Watch
- Watch Circle's EU reserve reporting for tighter terms under joint ACPR-EBA oversight
- Watch whether USDC's euro-area volume gains on USDT after the classification

Evernorth puts its $648M XRP pile to work lending

Stack
- Evernorth's XRP treasury sits at $648 million, per The Block
- Four counterparties named: Ripple, Kraken, Coinbase, BitGo
- XRP has no native staking yield, unlike proof-of-stake assets

Story
XRP pays nothing just sitting in a wallet, so Evernorth has to lend it out to earn anything. That means real counterparty risk, and Ripple being one of the four lenders concentrates it instead of spreading it.

Watch
- Watch Evernorth's next filing for actual yield rates and per-counterparty allocation
- Watch for any disclosed change in Kraken or Coinbase XRP lending terms

Thailand opens crypto ETFs Friday, CoinShares sees a slow start

Stack
- Hong Kong holds 0.42% of the $172.9B global crypto ETP pool despite its hub status
- Thai investors already route into Bitcoin via MFC's tracker fund since 2024
- CoinShares pegs Thailand's first inflows at tens of millions, not billions

Story
Regulating access doesn't create demand from nothing. Thailand's own feeder funds into BlackRock's IBIT have existed since 2024, so the new ETFs have to pull money away from something that already works.

Watch
- Confirmed launch date from MFC or ONE Asset Management
- First-week AUM versus the tens-of-millions marker
- Whether overseas ETF broker access widens past institutional and UHNW investors

Ripple Prime now lets clients trade stocks as perpetuals, 24/7

Stack
- Hyperliquid has processed over $1 trillion in cumulative perpetuals volume since launch
- Ripple's Hidden Road deal, the base of Ripple Prime, closed near a $1.25B valuation
- Traditional markets sit closed roughly 16 hours a day plus weekends, the exact gap this fills

Story
This is a credit and venue play dressed as tokenization. Ripple Prime holds the collateral risk, Hyperliquid supplies the price, and the client gets weekend stock exposure priced off a derivative of a derivative.

Watch
- Watch Ripple Prime's disclosed notional volume on these swaps next quarter
- Watch for funding-rate divergence on RWA perpetuals versus the underlying asset's normal volatility

XRP funds buck the ETF outflow trend as Bitcoin bleeds $151M

Stack
- Bitcoin ETFs: $262M out Wednesday, $151M net outflow for the week
- Ether ETFs: $190M weekly outflow after $542M the week before
- XRP ETFs: only category with positive weekly flows, $740K Wednesday

Story
Everyone's calling this a crypto risk-off week. The flow data says it's a Bitcoin problem specifically, XRP funds took in cash the same day Bitcoin lost $262M.

Watch
- Watch whether XRP ETF flows stay positive through the next SoSoValue weekly report
- Watch if Solana's eight-session outflow streak breaks

Circle plans USDC launch in 50 emerging markets, still stuck at 25% share

Stack
- USDC circulation: $73.3B, roughly a quarter of the stablecoin market
- Tether's USDT holds nearly 60% of that same market
- Circle paid $400M for Tazapay to enter new payment corridors

Story
Circle's expansion targets markets USDT already dominates. The growth story is about winning banks and payment firms with regulatory packaging, not catching Tether on volume.

Watch
- Does USDC's market share move past 25% in Circle's next circulation report?
- Does Circle disclose named bank or payment-firm integrations in the 50 target markets?

Stablecoin remittances cost 84% less than bank transfers, data shows

Stack
- $200 stablecoin remittance: $2 median cost vs $12.72 traditional, per Borderless.xyz
- Costa Rica's SINPE network completes only 73% of stablecoin payouts
- Mexico's SPEI settles payouts in 3 minutes with 98.6% completion

Story
The cost savings are real but the catch is completion rates, not fees. Costa Rica fails 1 in 4 stablecoin payouts while Mexico fails 1 in 70. The bottleneck is the local bank rail, not the stablecoin.

Watch
- Watch Costa Rica's SINPE completion rate in Borderless' Q4 report for infrastructure fixes
- Watch whether traditional remittance fees drop in response to stablecoin competition

Circle says it only keeps 7 cents per revenue dollar

Stack
- Circle kept ~7 cents net profit per revenue dollar in H1 2026
- $819M of $1.4B revenue went to distribution and transaction costs
- $214M of the remaining $473M was stock-based compensation

Story
This reads like a pricing war but it's really a disclosure fight. Circle published its cost math before Open USD has published a single fee number to compare it to.

Watch
- Watch for Open USD to publish an actual management-fee rate
- Watch whether Coinbase discloses its current USDC revenue share
- Watch for any major partner shifting volume within two quarters

BIS says bank deposit rates can throttle stablecoin growth, USDC most

Stack
- USDC supply dropped from ~$45B to under $25B in 2023 as bank rates topped 5%
- BIS study spans 2019-2025, a full rate cycle from near-zero to 5%+
- Circle's USDC showed the strongest rate sensitivity of any stablecoin tested

Story
USDC's 2023 outflows tracked bank deposit rates, not panic. Banks already hold a lever over stablecoin float and barely use it.

Watch
- USDC supply direction once the Fed starts cutting again
- Whether Circle adds holder-facing yield to blunt the rate lever

Stablecoin supply flat, but payment volume up 45% this year

Stack
- Stablecoin payments hit $482B through September, up 45% YoY, per Allium
- Transaction count jumped 71% to over 1 billion payments in the same period
- Total stablecoin supply grew just 0.4% since January, sitting near $305B

Story
Flat supply looks like a slowdown. It's actually the same dollars clearing 1.6x more payment volume than a year ago, which is why Visa, Mastercard and Stripe all showed up this week.

Watch
- Allium's Q4 data: does transaction growth keep outpacing supply growth?
- Do Visa, Mastercard or Stripe break out stablecoin volume in earnings calls?

Bitcoin ETFs lose $910M in two weeks as October stays red

Stack
- This week's outflow: $228.6 million, down sharply from the prior week
- Prior week's outflow: $681.1 million, the bigger single hit
- Combined two-week drain: roughly $910 million from spot Bitcoin ETFs

Story
The outflow pace slowed 66% week over week. That's not capitulation accelerating, it's a big redemption wave draining out.

Watch
- Watch for a third straight week of net outflows, even a small one
- Watch for a single day over $200M inflow breaking the current pattern

Full read: https://stackandstory.com/stories/bitcoin-etfs-bleed-910m-two-weeks

ETH ETFs just logged their worst month ever

Stack
- Ether ETFs: $955M in October outflows, the heaviest month of 2026
- Ether ETFs still hold just $610M net inflows for the full year
- Prior week saw $1.22B combined outflows, meaning the bleed is slowing

Story
A single October month erased a full year of Ether ETF gains. The pace is slowing but the hole it already dug isn't closing.

Watch
- Watch if Ether ETF YTD flows flip negative with ~$610M more outflows
- Watch if Bitcoin ETFs hit a third straight losing week

Mastercard builds a fraud and sanctions screen for stablecoin payments.

Stack
- Stablecoin Security launches in North America first, global rollout targeted for 2027
- Tool screens specifically for fraud and sanctions risk, not volatility or custody
- Gives Mastercard roughly a year of live data before wider deployment

Story
This isn't brand protection, it's a toll booth. Mastercard can't stop stablecoins from cutting out card rails, so it's trying to own the compliance layer instead.

Watch
- Watch whether Circle, Tether, or bank-issued stablecoins sign on as customers before 2027
- Watch for a competing cross-network screening product from Visa or a crypto-native vendor

Bitcoin ETFs' best day in a month came from one fund alone

Stack
- IBIT pulled $665.2M in a single day, more than the whole category's $526.7M net
- Fidelity's FBTC lost $83.6M and Grayscale's GBTC lost $54.9M the same day
- Spot Bitcoin ETFs are still down about $88M for October despite the rebound

Story
The $527M headline is one fund's number dressed up as a category trend. Every other issuer either lost money or flatlined the same day.

Watch
- Watch if IBIT keeps carrying inflows solo over the next two weeks
- Watch whether October closes net negative despite Monday's print

Stablecoins move $400M an hour, mostly off-hours

Stack
- Stablecoins move over $400 million per hour on average, per Coinbase and The Block
- Off-hours transfers dominate overall volume in the study
- Quarterly adjusted volume is projected to hit $1.5 trillion by end of 2027

Story
The off-hours concentration is the real tell here. Banking-hour clustering would mean exchanges shuffling collateral; off-hours dominance means payment and remittance demand running on its own clock.

Watch
- Does quarterly volume stay on pace for $1.5T by 2027, or stall below it
- Does off-hours concentration persist as volume scales, or revert to market-hours clustering

Switzerland lets retail buy a bitcoin ETF for the first time

Stack
- FINMA waived risk-diversification rules specifically for bitcoin, a first for any single crypto asset
- US bitcoin ETFs already hold over $97B in assets per CoinGlass, five years after Switzerland's 2021 qualified-investor fund
- Switzerland's 2021 crypto basket ETF was restricted to qualified investors only, unlike this new retail product

Story
This isn't Switzerland catching up to crypto. It's a regulator admitting one asset is now safe enough to break its own diversification rulebook for.

Watch
- Which issuer and bank actually launch the product, and on what timeline
- Whether FINMA extends the same single-asset exemption to ether or other coins next
- Early trading volume versus Switzerland's existing qualified-investor crypto basket fund

OCC sets a two-day redemption clock for stablecoin issuers

Stack
- Issuers must process redemptions within 2 business days under the final rule
- Rule and GENIUS Act both take effect Jan. 18, 2027
- OCC dropped its proposed presumption that affiliate deals violate the yield ban

Story
The headline is "stablecoins get a rulebook." The actual move is the OCC dropping its affiliate-yield presumption, which opens room for reward structures near the yield line.

Watch
- Watch for enforcement action against affiliate reward structures before Jan 18, 2027
- Watch for the Treasury-OCC joint AML/BSA rulemaking release date

Ether ETFs lose $1.08B in October, Bitcoin funds barely move

Stack

- Bitcoin ETFs: just $67M out, despite a 2.2% price drop
- Ether ETF YTD inflows now $485M vs Bitcoin's $809M

Story
This isn't a crypto ETF slump. Bitcoin funds are flat on the month while Ether funds just gave back a year's worth of gains in three weeks.

Watch
- October close: does the outflow pass $1.1B, a record since launch?
- Does ETH hold above $2,400 even as outflows persist?

ETF flows mirror Bitcoin's past, not its future, DWF finds

Stack
- Flow-to-past-price correlation: 0.54. Flow-to-future-price correlation: 0.03, per DWF Labs
- 7 of 8 Bitcoin drawdowns of 15%+ saw ETF outflows; all 9 matching rallies saw inflows
- Roughly 1/5 of ETF flows may be basis trades, long ETF and short CME futures, DWF estimates

Story
Big outflow headlines feel like a warning. The math says they're a rearview mirror, not a windshield.

Watch
- Watch for a drawdown that draws net inflows, breaking the 7-of-8 pattern
- Watch for CFTC data splitting basis trades from directional ETF buying
