AI-summarised brief · reviewed before publication

Bitget announced that suspected North Korean threat actors stole $351.6 million from its hot and warm wallets on September 24, 2026. The exchange confirmed that its cold wallets and most platform assets remained secure, and customer balances were unaffected. Withdrawals were temporarily halted while a comprehensive security review is conducted. Bitget hired Mandiant and SlowMist for investigation and has engaged affected blockchain foundations to freeze hacker wallets. The breach involved ETH, XRP, BNB, AVAX, USDT, and USDC across multiple chains.

💡 Why It Matters

· The loss underscores the growing sophistication of state‑backed cybercrime targeting crypto infrastructure, challenging the perceived safety of digital assets.
· It also signals a shift toward coordinated, cross‑chain defensive measures by exchanges and blockchain projects.

How Crypto Investment Strategies Have Evolved Over the Years

Crypto investing has evolved from simple coin purchases and private key storage to a diversified landscape that includes ETFs, staking, decentralized finance, derivatives, and tokenized assets. Early investors held Bitcoin through exchanges or peer‑to‑peer trades, focusing on scarcity and adoption. Ethereum’s smart contracts broadened exposure to decentralized applications, while the 2017 ICO boom introduced thousands of tokens, revealing that diversification alone does not mitigate risk. Decentralized finance enabled lending, borrowing, and yield farming, adding income potential and new smart‑contract risks. By 2026, U.S.‑listed ETFs such as Grayscale Solana Staking and Bitwise Solana Staking incorporated staking rewards, and tokenized real‑world assets surpassed $32 billion in value, linking blockchain infrastructure with traditional finance.

💡 The integration of staking rewards into regulated ETFs demonstrates how institutional frameworks are absorbing crypto’s native income mechanisms, reshaping risk profiles and accessibility for mainstream investors.

Bitdeer Sells Mined Bitcoin as BTC Tests USD 85K Mining Cost

Bitdeer, a Nasdaq‑listed Bitcoin miner, sold 288.4 BTC in the week to September 25, slightly exceeding the 288.1 BTC it mined and leaving the company with zero Bitcoin holdings. The sales occurred as Bitcoin hovered near USD 85,000, a price JPMorgan identifies as the industry’s average mining cost. On September 25 the cryptocurrency traded around USD 84,187, just below that benchmark, a level that can pressure miners’ cash flow and influence selling behavior. Bitdeer’s approach of immediately liquidating newly mined coins contrasts with firms that retain a treasury of BTC to hedge price risk. The broader market saw gains in most major cryptocurrencies, though some, like SXP, fell sharply, while others such as BAL and GRT posted double‑digit rises.

💡 By offloading every coin it mines, Bitdeer avoids exposure to price swings but also signals that even near‑break‑even prices are insufficient to justify holding BTC as a reserve. This underscores how tightly miner profitability is tied to short‑term price movements.

Why Ripple Just Gave AI Agents Their Own Payment Rail and What…

Ripple announced on July 10, 2026 the XRPL AI Starter Kit, a toolkit that equips autonomous AI agents with direct access to the XRP Ledger for payments, compute billing, and invoice settlement. The kit bundles an MCP server for documentation, an Agent Wallet Skill, and a Payment Skill, enabling developers to build machine‑to‑machine transactions without human approval. Ripple’s move follows a decline in XRP’s price, which has fallen 56 % from its July 2025 peak, but signals a strategic shift toward practical utility for the token.

💡 By granting AI agents a native payment rail, Ripple positions XRP as the backbone for automated commerce, potentially reshaping how businesses handle micro‑transactions and reducing friction in digital economies.

Circle Takes FX Onchain With 24/7 Stablecoin Settlement On Arc

Circle has launched StableFX on its Arc network, enabling approved institutions to conduct 24/7 stablecoin‑based foreign exchange settlement. The platform pulls request‑for‑quote pricing from multiple liquidity providers and uses a payment‑versus‑payment smart‑contract settlement, ensuring both legs of a trade complete together or neither does, thereby reducing principal risk. Users can settle immediately or net trades over programmable windows. StableFX supports USDC, EURC, and tokenized representations of AUD, BRL, JPY, CAD, and ZAR, while Circle supplies APIs and contracts without holding custody.

💡 By moving FX settlement onto a blockchain, StableFX eliminates traditional banking windows, offering institutions continuous, risk‑mitigated cross‑currency liquidity that could reshape daily treasury operations.

Developers Push Quantum-Safe Bitcoin Transaction Cost Below $70

An open optimization challenge has slashed the GPU cost of creating a quantum‑safe Bitcoin transaction from about $320 to roughly $67 in one week. Developers boosted RTX 4090 throughput from 146 million to over 820 million verified candidates per second and increased subset‑selection speed tenfold. The effort, led by 23 solvers on the pinning track and 17 on subset selection, builds on prior records and uses tools such as Opus 5, Fable 5.1, GPT‑6 Astra and others. Faster code reduces the brute‑force hash search that underlies quantum‑safe constructions, cutting required GPU‑hours. Although the transaction remains nonstandard, requires direct miner submission, and only protects unexposed public keys, the lower cost brings practical use closer. StarkWare still favors a soft fork for comprehensive quantum security long term.

💡 Reducing the compute bill transforms a theoretical safeguard into a viable emergency tool for high‑value Bitcoin holders.

Top 4 Cryptos to Buy Now: BlockDAG, Solana, Dogecoin, & Cardano Stand…

BlockDAG has emerged as the leading crypto to buy, launching a USDT buyback program that raises the payout from $0.02 to $0.03 for a seven‑day window, boosting potential returns by 1.5×. The program merges legacy and new BDAG holdings into a single buyback balance, automatically calculating payouts and expiring after a week, urging swift action. Solana, Dogecoin, and Cardano also feature, with Solana poised for an Alpenglow upgrade that replaces Proof of History with Votor and Rotor, promising faster finality and efficient data relay.

💡 The limited‑time buyback offers a rare, high‑yield entry point for investors, while Solana’s upcoming consensus shift could redefine layer‑1 performance, reshaping competitive dynamics.
