Someone on Reddit just lost ~$2,100 in BTC 🥲 His best guess? He copied his seed phrase between two hot wallet apps to test things out and forgot to clear the clipboard. At some point, something silently read it. Funds gone. No way to reverse it. The thing is: a seed phrase isn't like a password. You can't just change it after the fact. Whoever has it, has everything. Every time it touches a clipboard on an internet-connected device, that's a window. And windows get found. With a hardware wallet, you never have to move it in the first place. Switch apps? Just reconnect. The phrase never leaves the device. 🔐 Hope it never happens to you 💙 But if you're still copying seed phrases between apps to "just test something" — this is the sign.

🎲 Generated your 24-word seed phrase without tracking your dice roll count? You may have 24 words, but not the 24-word security. Keystone's latest firmware closes that gap 🔐 The old flow: roll until you've got enough numbers, fill in your words, done. But word count and entropy aren't the same thing — and most implementations never check whether the second one is actually there. So now: 🔐 12-word phrase → minimum 50 dice rolls 🔐 24-word phrase → minimum 100 dice rolls The math behind it: A standard six-sided die gives you ~2.58 bits of entropy per roll. 50 rolls ≈ 129 bits → matches the 128-bit security a 12-word phrase needs. 100 rolls ≈ 258 bits → matches the 256-bit security a 24-word phrase needs. Roll only 50 times and force a 24-word phrase anyway, and the math doesn't care how many words show up on screen: you're carrying 12-word entropy in 24-word packaging ⚠️ That's not just weaker security — it's worse. It's security you believe is stronger than it is. Which is exactly why Keystone now hides the 24-word option entirely until you've logged 100 rolls. Not added friction. A refusal to let your phrase lie to you about what it can withstand. 24 words should mean 256 bits of real security — not 256 bits of false confidence. 🛡️

@0711_BTC Congratulations, fam!

I became a father for the second time 🥰 Block: 954147

@thestellaverse_ @molusol @OneKeyHQ @Tangem Thank you, Stella 🤩

@molusol I use @OneKeyHQ for DeFi @KeystoneForBTC for BTC @Tangem my bull run bag

Ledger’s been my only hw wallet so far. Looking to add a second one to the mix, any recs? > I care more about safety than price.

@BULLBITCOIN_ Keystone 🙌

You shouldn’t have to choose between convenience and security. Connect any of these hardware devices to your Bull Wallet and sign transactions offline! What’s your favorite signer?

@CiccioMadonna @christine_dkim Congrats, Franc 🙌

thrilled and humbled to be listed in the "Bitcoin Contributors" section of the @christine_dkim's blog. thanks a lot. christinedkim.substack.com/p/bitcoin-cont…

@UnruggableGG @BULLBITCOIN_ @BtcpayServer @spacebull @r0ckstardev @BTCsessions @thgO_O @MartinaG2702 Bitcoin bulls spotted 🐂

They built cages. We built exits. @BULLBITCOIN_ x @BtcpayServer We don't ask. We build.

WE'RE BACK ⚡️

Every year, our Bitcoin community retells this story 🍕 This year, we built something to capture its significance. Pizza Day Limited Edition Keystone 3 Pro for $149 with code 'Pizza'. Ends by May 24. Grab yours before it's gone ⏳

Attending @MadBitcoin_2026 in Spain? 🇪🇸 Stop by @Alvaro_DMaria's BTC consulting booth, and check out the Keystone hardware wallet while you're there. Got yours already? Tell us what convinced you 👇

"Bitcoin Under the Worst Possible Conditions." First Bitcoin Magazine cover. BTC was $5. The world laughed. A teenage Vitalik and a few believers printed magazines anyway. 14 years later? Still the loudest voice in Bitcoin. Happy 14th, @BitcoinMagazine 🎂

Your BTC transactions just got safer ⚡️ Keystone v2.4.2 now shows SIGHASH flag details before you sign, including warnings for risky flags like SIGHASH_NONE, SINGLE, and ANYONECANPAY. More clarity. No more blind signing. Update today and see exactly what you're approving 💪

Screenshot your seed phrase? SparkCat is coming for you ⚠️ Kaspersky uncovered SparkCat's new tricks: hiding in fake corporate apps and food delivery software, using code virtualization to dodge detection. Removed from official stores, it's now spreading through shady third-party app stores. How to stay safe: → Never install unknown apps, even from legit stores → Avoid third-party app stores entirely → Don't grant unnecessary permissions The real fix: Generate and store your seed phrase offline with a hardware wallet. Physical isolation = complete immunity to OCR stealers like SparkCat. Your crypto. Your responsibility. Protect it right.

@bitcoinpolicy This comes off like recycled FUD. Bitcoin wasn’t just designed to be decentralized in how it runs, but also in how it’s perceived. Satoshi Nakamoto stayed anonymous for a reason, removing any central figure that could influence or overshadow the system.

The enduring genius of Bitcoin is that the Satoshi mystery does not need an answer. A monetary network secured by cryptography and game theory, rather than on trust in any individual or institution, does not depend on who Satoshi is or on whether Satoshi is ever found. Every other monetary system in history has depended on trusting someone. Bitcoin is the one that doesn't.

Stop asking "which hardware wallet should I buy?" Start asking "which attack vectors does it actually close?" 💡 Most hardware wallets leave the same critical gaps open as the hot wallets you're trying to escape. Going offline solves one problem, but attackers have seven other ways in. 1. Weak entropy breaks everything Your device generates keys "offline" using predictable algorithms - the same flaw that drained Lubian Mining users for $100M+. Keystone uses the two secure elements to boost randomness for a strong seed phrase. 2. Blind signing makes you vulnerable Most hardware wallets can't decode smart contract calls. You're trusting whatever the dApp shows you: one malicious interface and your "secure" device signs everything away. Keystone decodes transactions on its air-gapped screen before you sign to give you offline safety and signing clarity. 3. Tampered before you open the box Devices get intercepted during shipping, backdoors installed, then resealed. Keystone ships with tamper-evident packaging and on-device verification to give you the peace of mind and confidence. 4. Closed source = blind trust Can't audit the code? You're trusting strangers with your life savings. Keystone is fully open-source, making it open to researchers and security experts worldwide for verification and collaboration. 5. Physical threats expose everything One seed phrase = total loss. Keystone supports three independent seeds. So, hand over the decoy, protect your real stack and yourself. 6. Single point of failure One secure element means one vulnerability ends you. Keystone splits seeds across multiple SEs from different makers, making it twice as secure as most hwws. 7. No anti-tamper = silent theft A physical attacker opens your device, extracts keys, and steals your funds. You'd have a really low window to act. Keystone wipes data instantly when breached, leaving the attackers with a bricked device. 8. Side-channel attacks bypass everything else: These attacks push the SE to its limits and expose keys to the attackers. Multi-SE architecture makes this exponentially harder for the attacker and increases your time window to move your funds to safety before it's too late. If your hardware wallet meaningfully reduces these risks, then you’re not just “offline.” You’re actually secure.

Happy Birthday, Satoshi ⚡️ 51 today (according to his P2P Foundation profile). Obviously fake. But April 5 wasn't random: 1933: Roosevelt's EO 6102 - the US gov confiscates civilian gold. 1975: Americans regain the right to own gold. Satoshi picked the date that symbolizes why Bitcoin exists. A rebuke to government overreach. A declaration for decentralized money.

⚡️ Time to update your BTC-Only Keystone 3 Pro! The latest firmware 2.4.0 brings critical security improvements to make your Keystone more robust. Update today, and make sure your circle sees this 🤝
