New idea: The Bitcoin Maxi Crematorium. Are you a hardcore Bitcoin maxi who wants to live forever in Bitcoin's Cyber City? Welcome to the Bitcoin Maxi Crematorium. When your time comes, we cremate your body and use the energy generated to power Bitcoin miners. In a sense, your final contribution is transformed into hashes that help secure the Bitcoin blockchain. You may be gone, but your energy will forever be part of the network. Proof of Ash.

In December 2022, a series of Russian propaganda films warned Europeans that fuel shortages would soon leave them riding horses. Three years later, while Europeans continue to drive their cars, the Kremlin is considering a complete ban on diesel exports as severe fuel shortages spread across more than 60 Russian regions.

My attempt to protect users from scam apps on the @AppStore has gotten my Apple Developer account flagged for termination - ironically, for "dishonest activity". Unless it's reversed by June 30, all new installs of Sparrow Wallet will fail, and development on macOS will end. The context: since 2023, more than a dozen fake "Sparrow" apps have appeared on the App Store, as recently as April this year. Users have contacted me after losing their savings, in some cases their life savings, to these impersonators. I'm the developer of the real Sparrow Wallet, a desktop app, and I hold the registered US trademarks for the name and logo. I have publicly warned @Apple and the community about these fake apps from early 2024, but they keep appearing. The app @Apple flagged was a placeholder that was never published. Its only purpose was to warn users that Sparrow is desktop-only and that other "Sparrow" apps aren't mine. This approach may have been misguided, but there was nothing dishonest about it. I'm confident this is an automated misclassification that Apple would reverse on review - but I may be terminated before a human ever looks at my appeal. The cost would fall on @Apple's own users: blocked installs and no updates for a tool people rely on, which opens the door for more fakes. If you value Sparrow, a repost would help. @AppleSupport

@statusquont @bitcoinfool @Apple Didn’t work. App (with the screens below) was rejected for having “placeholder content” and only “demonstrating a concept”.

Last month, I asked a Bitcoin miner operating in Sweden what his electricity cost him per kWh The answer was a negative number Most of his revenue isn't even coming from mining Like Bitcoin itself, Bitcoin mining is incredibly antifragile.

Kudos to ChainQuery for resurrecting and enhancing @khannib's "UTXO Repartition" charts that analyze all of the different types of locking scripts currently used to secure BTC. chainquery.com/reports/utxo-r…
