Market signal

A weekend "Black Monday" scare fades into a Monday chip-stock rebound, but bitcoin's weekly close lands under its support band. Thin weekend liquidity turned a late-Saturday wipeout in AI-chip-linked perpetuals (Micron, SanDisk, SK Hynix) into a brief panic – traders cited figures from roughly $33m to $52m liquidated across those contracts – with "Black Monday" trending on crypto Twitter as the move landed on the 39th anniversary of the 1987 crash; bitcoin slipped to a Sunday low near $80,595 and ether briefly tanked to about $2,360 before both bounced. Monday's Nasdaq rebound (up more than 1%, led by chip names) pulled bitcoin back above $83,000 intraday before it faded under $82,000; its weekly candle closed at $82,000, below the $82,500–$82,800 zone traders had been watching as support. The Coinbase Premium Index, a proxy for US spot demand, fell to -0.14, its weakest since late June, and Coinglass tallied roughly $334m in total liquidations over the weekend. CCN · Cointelegraph

Markets & flows — ETFs, stablecoins & on-chain

Bitcoin ETFs post a fifth straight net-outflow week; ether ETFs fare worse. US spot bitcoin ETFs shed a net $228.6m across the week of October 12–16 per SoSoValue-sourced data, including $82.39m out on Friday alone (IBIT -$71.78m, FBTC -$10.61m). Spot ether ETFs lost roughly $319–320m over the same week – their third straight week of redemptions – with Friday's $69.68m outflow attributed entirely to BlackRock's ETHA, which has now gone fourteen straight sessions without a single inflow day.

XRP funds snap a 13-week inflow streak as the token reclaims $1.31. Spot XRP ETFs posted a modest net outflow of about $1.84m over the week, ending their longest run of inflows since launch, even as XRP's price recovered its $1.30 support alongside the broader market bounce. crypto.news

Strategy keeps buying through the drawdown, and doubles its preferred-stock buyback capacity. Strategy (MSTR) disclosed in an October 19 8-K that it bought 267 BTC for $22.1m (avg. $82,900) in the week to October 18, lifting its holdings to 848,517 BTC; the same filing says its board raised the repurchase authorization for its STRC preferred ("digital credit securities") from $2.0bn to $3.0bn.

The industry — exchanges, miners & infrastructure

Circle discloses what USDC's distribution deal with Coinbase actually costs, as rivals offer partners a bigger cut. Circle's H1 2026 figures show $1.395bn in total revenue and reserve income (of which $1.32bn was reserve income), against $815.8m in distribution and transaction costs – $655.3m of it paid to Coinbase under their USDC partnership – as competing stablecoin issuers try to win over distribution partners with richer revenue splits. Coinbase itself also backs a rival network, Open USD, complicating its incentives. CoinDesk

Coinbase expands into stablecoin-backed cards for businesses via Marqeta. Coinbase will custody the stablecoins and handle conversion to and from traditional currency, with settlement on its Base network, while Marqeta issues the cards and processes payments for enterprise customers; neither company has given a launch date, fees or which stablecoins will be supported first.

No bitcoin-miner-specific news (hash rate, hosting or AI-pivot deals) cleared the bar this window; the mining complex traded with the broader AI-stock wobble rather than on company news.

Policy & regulation

The SEC clears a first-of-its-kind binary options product built on Coinbase, Robinhood and Marathon metrics. An SEC order granted accelerated approval, dated October 13, for Cboe to list cash-settled binary options tied to companies' own reported KPIs – among the initial reference metrics are Coinbase's trading volume, Marathon Digital's bitcoin output and Robinhood's customer and revenue figures, with Robinhood set to be the first retail broker offering them. Trading hasn't started: Cboe's clearinghouse still needs a separate registration to clear the contracts. SEC order

The Chatter

Rekt Capital (X, via Cointelegraph): argued that bitcoin's weekly close below the $82,500–$82,800 zone sets that band up as resistance on any retest, and that a failed retest opens the door to a renewed slide below $80,000 – his own chart read, not a house call. Cointelegraph

Glassnode (Week On-chain, via FXStreet): wrote that the heavy selling behind early October's decline has eased, but fresh demand hasn't stepped in to replace it, and that it expects only muted upside for bitcoin until ETF and spot buyers resume accumulating – a cautious on-chain read, not a directional call.
