⚠ ZachXBT reported a breach: the “GANA Payment” project was hacked a few hours ago. The attacker took more than $3.1M and erased the trail through Tornado. Sad case, though instructive. Each incident forces teams to tighten audits, rethink architecture and treat other people’s funds responsibly.

📊 Coinbase is working on a prediction market with Kalshi, along with tokenized stocks and ETF trading. The announcement lands on 17 December. No surprise prediction markets keep popping up. People have always tried to guess the future, only now the wagers are digital, global and a lot more deliberate.

💰 The Marshall Islands are rolling out a universal basic income program through the Lomalo digital wallet on the USDM1 stablecoin, and it’s far more than a local test. This is the first real showcase of how on-chain rails can make government payouts more efficient.

🛡 Theft of private keys has turned into a full-blown industry, complete with malware and seed-phrase scanners targeting wallets and backups. The safer mindset is simple: treat every local device as potentially compromised. No digital seed phrases, rely on multi-party approvals, and build storage setups that don’t collapse from a single point of failure.

⚠ Vitalik Buterin thinks quantum computing could break elliptic-curve cryptography before 2028. Not a panic trigger, more of a push to move. Quantum-safe math, lighter layers, sharper wallets, real privacy — the list writes itself. The pace around us isn’t slowing, and blockchains don’t get a grace period. Move, or get rewritten by time.

🔗 ICP is still the only blockchain that actually runs full apps onchain. Dominic Williams noted that everything built on Internet Computer kept working during the Cloudflare outage. Same story every time. We preach decentralization while the stack leans on single points of failure.

⛓ Mastercard teams up with Polygon, making it possible to send crypto to usernames instead of wallet addresses. It's gonna be a huge payoff in convenience. I reckon it's a rare moment where the tech finally behaves like people do.

😐 Bybit picked a name for its new mascot. The market looks like a washing machine right now, meanwhile the exchange held a public vote and crowned the cat. Meet Billy. Chaos never stops, but there is always time to smile at a cat.

⌛ Aave Labs launched a new app. Savings, earning, and borrowing on-chain now live inside one ecosystem, exactly where they belong. Always refreshing to see teams that think long-term and push in the right direction. Mass adoption grows through simple things: clearer UX, fewer steps, smoother integrations.

💀 Phishing is still alive in 2025. If your email ever leaked through OpenSea, Ledger, Coinbase or any other big service, it already sits in some darknet list. So messages like this one keep landing in people’s inboxes. Plenty have seen it already. This only proves how much data companies scoop from us and how little they care about guarding it. We must protect ourselves because no one else will.

🐳 Vitalik Buterin showed a new privacy framework called Kohaku at Devcon. Modular architecture, integrations with Railgun and Privacy Pools, plus experiments with mixnets and ZK browsers. Love watching how Vitalik keeps pushing Ethereum forward. Privacy becomes the real frontier.

🚫 DappRadar is shutting down after seven years. Back in 2018, hardly anyone cared about “decentralization,” and Web3 felt like a garage project for a few stubborn optimists. I remember watching their dashboards during the early DeFi chaos and thinking: finally, someone is bringing order to the madness. Now they say the platform no longer pays for itself. The community reacted fast and plenty of people want to support the team.

😱 Should’ve stayed asleep. A wallet silent for five years suddenly woke up, dumped 14.45 million ADA and ran straight into the wall of low liquidity. Result: a six-million-dollar loss. Five years of waiting for one bad move. Markets punish absent minds, and once the trade is done there is no rewind button.

🙂 I just love the fact that every cycle produces a “new Vitalik,” and Crypto Twitter instantly turns him into a meme. The industry keeps shifting, projects grow up, markets mature, yet Vitalik stays as the permanent mascot of crypto’s strange, bright, slightly chaotic spirit. Some things keep spinning, some things stay exactly where they are.

☄ Peter Schiff hasn’t even argued with CZ yet and already called out Michael Saylor. He’s convinced that no matter what happens to BTC, Saylor’s strategy is doomed. Funny how every loud critic ends up adding a bit more shine to the asset they want buried.

➡ Brian Armstrong reminded everyone of a simple truth: action produces clarity. When everything feels foggy, movement becomes the only compass. Even a wrong step outlines a path that wasn’t visible a moment earlier. The irony is that we all know this and still ignore it. Pulling yourself out of that still point feels harder than it should.

🖥 Vitalik Buterin said he hates crypto apps that rely on Google login. If Web3 keeps leaning on Web2 crutches, the whole thing starts to look a bit pointless. That old paradox shows up again. Convenience pulls people in fast, but the same comfort strips away security and the original spirit.

👋 Group chats in ChatGPT are now in testing, and it feels like the next phase of how people talk online. One room for friends, family, coworkers and an AI shifts the whole idea of digital conversation. We moved from SMS to messengers. Now we have shared chats with an AI.
