Zero-knowledge computing project Cysic suspended its cross-chain bridge on October 17 after an attacker minted 10 million CYS tokens and cashed part of the supply out for about 306 ETH. The foundation says user wallets and its mainnet were untouched.
Charles Schwab has opened spot bitcoin and ether trading to all eligible clients, the brokerage said on its October 15 earnings call. The firm holds $13.33 trillion in client assets and plans to add three more coins by year-end, though trades cost 0.75% each.
Crypto.com and Novig filed federal suits on October 16 to stop Missouri from enforcing its sports betting laws against their event contracts, arguing only the CFTC can regulate the products. Four other firms that got the state's cease-and-desist letters have not sued.

The European Central Bank will test a digital euro for a year before any public rollout, its president said on 17 October. The plan hangs on EU lawmakers passing the law by the end of 2026, a deadline that is far from certain.

Cysic says the exploit was contained, with no user assets stolen and its mainnet untouched.
Our read: On-chain data supports the limited realized haul and the frozen 2.8 million CYS, and the mainnet does appear unaffected. But Cysic has not put a final dollar figure on the loss, has not named the security firm it hired, and has not said how it will handle the 7.2 million extra tokens already sold into the market.
A $13 trillion brokerage putting spot bitcoin and ether in front of every client marks crypto's arrival in the mainstream.
Our read: The rollout is real and the reach is large: Schwab reported $13.33 trillion in client assets and about 1.2 million new accounts in the quarter. But the offer is still two coins, trades cost 0.75% (more than most exchanges), transfers are not yet live for everyone, and the service skips New York and Louisiana.
Crypto.com and Novig say their sports event contracts are federally regulated derivatives, so only the CFTC can oversee them and Missouri's gambling laws do not apply.
Our read: Both platforms are registered with the CFTC, which gives the argument a real basis. But federal appeals courts have split on the point, no Supreme Court ruling exists, and Missouri rejects the claim outright. Whether preemption wins in this case is unsettled and rests with the courts.
Russia says it can bring crypto under a licensed, supervised system by routing all trading through approved intermediaries and barring transfers to private wallets.
Our read: The law is in force and 13 exchanges, including Sberbank and VTB, are licensed. But the self-custody and peer-to-peer limits are hard to enforce on global networks, the central bank has not said how it will police them, and a Sberbank executive expects only about 20 percent of volume to move onto licensed venues at first.

Mining bitcoin in 2026 pays for very few people. A single machine at home usually spends more on power than it earns. Here is what a coin really costs to produce, a worked example with live difficulty and price, and why your electricity rate decides the outcome.
Quantum computers could one day crack the signatures that protect Bitcoin wallets. No machine is close yet. Here is what the threat is, which coins are exposed, and the defense work already under way.
Coinbase, the custodian of roughly 5% of all bitcoin, published a paper on 13 October urging developers to start building quantum-resistant defenses now. No computer can break bitcoin today. The company says the fix could take years, so the clock has started.
Charles Schwab has opened spot bitcoin and ether trading to all eligible clients, the brokerage said on its October 15 earnings call. The firm holds $13.33 trillion in client assets and plans to add three more coins by year-end, though trades cost 0.75% each.
Payward, the company behind Kraken, has agreed to buy Saldo Bank, a small lender in Lithuania. The deal would give the exchange something a crypto firm rarely holds: a full European bank license. It is not done yet.
Visa says its USDC prefunding service is now in commercial production, letting businesses fund cross-border payouts with the stablecoin in near real time. Inyo Global is the first processor to switch it on.

Solana will switch on its Alpenglow upgrade on October 21, replacing the TowerBFT voting system it has run since 2020 and targeting transaction finality of about 150 milliseconds, down from roughly 12.8 seconds. SOL holders need take no action.
The onchain contracts stay live, but Blur's website and its Blend lending service both close on November 12. Monthly trading volume had already fallen from $1.43 billion to under $7 million.

CME Group will list Uniswap and Bitcoin Cash futures on October 19, cash-settled contracts it certified with the US CFTC on September 23. The launch gives institutions a regulated way to trade two tokens whose prices fell back after the news.
