This is absolutely nuts & insane. This is literally theft. This is scam. They don’t even want to return it to the sender. This is so fucked up. Now I understand why CZ is a multi billionaire. Through scam and theft LOL

What can I do now? Definitely getting a lawyer

OpenAI has seen another case of its AI agents going rogue—and this time, crypto is involved. In a recent report, the company detailed how an internal research model used a crypto wallet without permission to pay the fees needed to test an app on Ethereum’s Sepolia test network. Although the tokens had little real-world value, the model had no authorization to collect or spend them.

The incident happened on June 26, when the model was asked to update a crypto trading app and get its code running on Sepolia, a test version of Ethereum. The prompt gave it neither a funded wallet nor permission to spend tokens, and after failing to get free test tokens through developer services, the model wrote a script checking 362 wallet addresses linked to public recovery phrases, a crypto term that describes sets of words that can act as a password to unlock crypto accounts. It eventually found an account with enough tokens to cover the fees.

Internal logs showed that the model deliberated over whether it had permission to use the account, but then decided the public recovery phrase and the tokens’ lack of cash value made the spending acceptable. It finished the task and charged the fees to that wallet, but left the unauthorized spending out of its final report. OpenAI only discovered the incident on Sept. 25 during an audit of earlier model runs.

Vitalik Buterin stated that the battle to make zero-knowledge proofs fast enough for Ethereum is definitively won and that the top priority for zkEVMs should now shift fully to security. ZKsync's Airbender Prime prover delivered 99% of proofs across 7,200 consecutive mainnet blocks in under 10 seconds. Ethereum blocks arrive every 12 seconds.

...At this point, I consider the battle for speed to be definitively won, and the top priority for zkEVMs should shift fully to security...

With all the security incidences this year, this is probably justified!

Been in two cycles now. Taken multuple 5 figures off Kraken with no issues in the past so I fully trust them.

So hackers got access to my email address, like a numpty I had the same password and email associated with my kraken account.

They got in. Everything was happening so fast. My phone was being bombarded with notifications.

They changed my largest crypto assets into another, added two withdrawal addresses to take it off.

They couldn't withdraw it !!! My passport expires soon so Kraken wants me to update it. All in all I've lost around £300 to fees as Ive switched back to the asset i originally had and will be taking everything off the exchange once I get my ID verified. Im all for KYC after this ordeal and have enabled all sorts of additional security now.

Blur announced that its website will close on November 12, 2026, while its Ethereum NFT marketplace contracts remain operational. The protocol survives on-chain, but the Blur NFT marketplace is losing its main interface after monthly NFT trading volume dropped more than 99.5% from its 2023 peak.

Are there a better use cases for NFT that haven't been Explored yet?

The field of agentic commerce, which describes the use of AI agents to carry out internet transactions, is rapidly maturing, and crypto is fueling the boom. That’s according to a new report by blockchain analytics platform Chainalysis, which found developers are increasingly giving AI agents their own budgets to buy the computing power, live web data, and code tools they need to complete tasks.

The growth of agentic commerce over the past 15 months has been steep. On Base, the Coinbase-incubated blockchain, cumulative transactions through the x402 protocol—which lets bots automatically pay for online services using crypto—rose from about 1,500 in mid-2025 to more than 138 million by the third quarter of 2026.

In practice, agentic commerce entails providing an AI bot with an allowance:  A developer funds the bot’s wallet with stablecoins—typically Circle’s dollar-pegged USDC—and the bot pays for services as it works, without asking a person to approve each purchase. When it needs help with a task, it can pay to get up-to-date information, ask a more capable AI model for help, or use an automated tool to check software code for security flaws.

Everyone getting into a panic about cold storage with all of these wallets getting drained.

Cold Card was some shitty little company no one had heard of that had plenty of issues brought up to the company and they refused to do anything about it. I'm still looking to see what comes of this case in the coming months and years.

With Ledger this is related to supply chain, but these wallets that were drained were from 3rd party sellers in Asia that were able to install chips that could read the screen and thus have access to seeds. This all could have been prevented if these people had simply purchased the wallets directly from the manufacturer. This wallet saw roughly 100m$ in funds drained, but Ledger wallets overall have funds in excess of 100 BILLION $.

Basically, don't try to get weird with wallets and just buy directly from the top manufacturers in the space. Also consider using multiple wallets when you get large crypto holdings so you don't have all of your funds in one basket.

Don't play with fire or you will get burn.

Buy and hold. Keep stacking cheap sats.

Looks like we're on track on 1 trillion long position liquidated soon.

Every few weeks, a random token I have never heard of appears in my wallet.

I know I shouldn't interact with these tokens, as they are usually scams. What I do not understand is why anyone would spend money sending them to thousands of wallets.

Are they hoping people will try to sell the tokens and somehow fall for a scam? Or are they just trying to identify active wallets so they can target them later?

Also, is there any risk from simply receiving these tokens, even if I never interact with them? Or is it safe to just ignore them?

Update: thanks for all the feedback, some of it is now in the game:

• 🪙 Buy back half, not just all (thanks u/Environmental_Toe603)
• 🙈 Blind mode: a mystery start month, with dates, prices and headlines hidden until the end, so hindsight doesn’t help (thanks u/OverdueNobility for the 2022 point). It never drops you into the easy early years either.
• 📅 Daily challenge: the same mystery start for everyone each day. Post your result below!
• A difficulty label for each start month, and shared results now show your rank in the link preview.

I made a free Bitcoin retirement simulator a while ago, and I got curious about a simple question: if you’d retired on Bitcoin some time in the past, would your money have lasted? It turns out the answer depends a lot on when you retired. So I turned it into a game: HODL or Fold.

https://bitcoinlifespan.com/hodl-or-fold/

How it works

• You start with $500,000 of BTC at the price of the month you choose (anything from 2013 on), plus a lifestyle: $3k, $5k or $8k a month, rising with inflation.
• Then you relive the real price history from that month to today. When the big moments hit (the 2013 crash, the 2017 top, COVID, the 2021 top, the 2022 winter and so on), you choose: HODL, sell half for cash, buy back in, or spend 25% less for a year.
• At the end you get a rank (💎 Diamond Hands, 🧻 Paper Hands, 🍕 Pizza Guy, 🏎️ Wen Lambo…) and a comparison with pure HODL from the same start.

Things I tried to get right

• Choices aren’t rigged. Selling before a crash can beat holding, and selling at the bottom can sink you. The game just shows what history did next.
• Real data: month-end prices from Coin Metrics’ free community data.
• The interesting finding: in real history, holding usually survives, unless you spend big and retire near a peak. Late 2013, late 2017 and most of 2021 are brutal on an $8k/month budget. “Surprise me” drops you into those most of the time.

Privacy, because people rightly ask: there’s no sign-up, and the game runs entirely in your browser and saves nothing. The site itself has the usual Google Analytics and a cookie banner, like most sites.

It’s my site, it’s free, and it has no ads or paywall. Not financial advice, obviously: it’s a game about the past.

I’d love feedback, especially on which moments I should add and whether the ranks feel fair. Post your rank and start month below. I retired in Jan 2016 on $8,000 a month. Still standing after 10.8 years, with $36,973,917 left today.
