Crypto brief: August 11, 2026

Why today matters

Corporate bitcoin balance sheets, ATM compliance, and altcoin ETF cleanup collided with Bitcoin governance cleanup on Monday’s tape. Strategy sold another 1,690 BTC to fund preferred-stock buybacks while Bitdeer posted a wider Q2 loss even as hashrate jumped. Australia’s financial-crime regulator pulled 96 crypto ATMs offline, and Grayscale asked the SEC to withdraw Cardano, Polkadot, and Hedera ETF registrations.

On protocol desks, BIP editors removed Luke Dashjr after the BIP-110 minority fork stalled, and Ethereum’s public Strawmap put post-quantum security and L1 privacy among its north stars. U.S. spot bitcoin ETFs flipped to a net outflow after last week’s inflow streak. As of the 00:27 UTC market snapshot on August 11, 2026, Bitcoin traded near $63,909 (−1.7% 24h), Ether near $1,871 (−2.4%), and Solana near $75.90 (−1.1%).

Below are the filings, regulator notices, and primary docs that shaped the day. For more context, see our Bitcoin history, Ethereum history, and yesterday’s BIP-110 fork stall reaction.

  1. Strategy sells 1,690 BTC to fund STRC preferred buybacks

    In an August 10 Form 8-K, Strategy said it sold 1,690 bitcoin between August 3 and August 9 for about $108.6 million at an average $64,262, leaving holdings at 840,447 BTC. The same filing shows $653.1 million of MSTR ATM proceeds in the week, with $650 million added to a USD reserve that stood at $4.65 billion as of August 9. Sale proceeds funded repurchases of 1,152,020 STRC preferred shares, underscoring the firm’s shift from pure accumulation toward servicing its digital-credit capital stack.

  2. AUSTRAC suspends Cryptolink, taking 96 crypto ATMs offline

    AUSTRAC suspended Cryptolink Pty Ltd’s virtual asset service provider registration for three months from August 9, ordering the operator’s 96 cryptocurrency ATMs offline. CEO Brendan Thomas said the firm met an earlier enforceable undertaking but later failed basic threshold transaction reporting and did not answer regulator information requests. The action follows an October 2025 undertaking and a paid $56,340 infringement notice, and it keeps Australia’s Crypto Taskforce focus on cash-to-crypto kiosks.

  3. Grayscale withdraws Cardano, Polkadot, and Hedera ETF registrations

    On August 7, Grayscale Investments Sponsors filed Form RW withdrawal requests for its Cardano, Polkadot, and Hedera Trust ETF S-1 registrations. The Cardano letter says the sponsor “does not intend to proceed with the planned distribution,” confirms the statement was never declared effective, and states that no securities were issued or sold and no preliminary prospectus was distributed. Parallel Polkadot and Hedera RW filings use the same sponsor-initiated language, so the pull is a product decision rather than an SEC rejection.

  4. BIP editors remove Luke Dashjr after BIP-110 conflict charges

    Mark “Murch” Erhardt motioned on the Bitcoin Development Mailing List to remove Luke Dashjr as a BIP editor, citing conflict of interest around BIP-110, minimal recent editorial work, and broken coordination. Dashjr called the accusations false. Bryan Bishop later confirmed that “the individual known as Luke Dashjr is no longer a permissioned user on the BIP content repository,” closing a governance fight that followed the stalled BIP-110 minority fork.

  5. Ethereum Strawmap elevates post-quantum security and L1 privacy

    The Ethereum Foundation Architecture team’s public Strawmap frames L1 upgrades through 2029 around five north stars, including a post-quantum L1 via hash-based schemes and a private L1 with shielded transfers. The living draft also targets fast finality, gigagas L1 throughput, and teragas L2 scale, and it stresses that the map is a coordination strawman rather than an official prediction. Monday’s desk chatter compared the new priorities with the 2023 Merge-to-Splurge diagram, where quantum and privacy were not yet first-class roadmap boxes.

  6. U.S. spot bitcoin ETFs post $50.7M net outflow on August 10

    Farside Investors’ all-fund table shows U.S. spot bitcoin ETFs with a combined −$50.7 million net flow on August 10, interrupting last week’s multi-session inflow run. Fund-level prints were mixed, including a −$52.0 million GBTC figure against a +$37.1 million print elsewhere in the row. Flow days this choppy matter more for positioning than for single-day price calls, especially with BTC still holding the low-$60,000s on the site snapshot.

  7. Trepa and Fireplace shut prediction venues as Kalshi-Polymarket dominate

    Trepa and Fireplace told users Monday they are winding down and set a September 30 withdrawal deadline, announcements that landed about 90 minutes apart. DefiLlama-tracked venues show Kalshi and Polymarket taking about 93.3% of the past 30 days’ prediction-market volume, leaving little oxygen for niche Solana games or Polymarket terminals. Trepa’s founders said retention failed under a one-hour daily bitcoin-price round design that could not scale without thinning the pools their payout math needed.

  8. Bitdeer Q2 revenue jumps to $228.8M while net loss widens to $92.3M

    Bitdeer’s August 10 Exhibit 99.1 reports Q2 2026 revenue of $228.8 million, up from $155.6 million a year earlier, but a gross loss of $8.5 million and a net loss of $92.3 million. Self-mining hashrate in owned datacenters rose to 73.0 EH/s from 16.5 EH/s, yet BTC held fell to 150 from 1,502, and management leaned on AI/colocation leases such as the Tydal, Norway Volta deal. A separate 6-K the same day refreshed a $1 billion Class A ATM shelf, keeping equity issuance capacity beside the AI pivot story.
