🚨 Watch out for EIP-7702. A leaked private key lets a malicious 7702 contract drain native tokens instantly in a single tx — no extra clicks needed.

Phishers love it: one careless signature and the wallet’s gone. Revoking delegation won’t help once the key leaks, move funds to a fresh address. Only sign what you fully understand.

🐰 Tiffany Lai, founder of Taipei Blockchain Week, just released a blockchain alphabet book for kids. Even Erica Kang (wife of NEAR’s Illia Polosukhin) gave it a nod. Packed with crypto easter eggs, it’s fun for adults too.

Teach it early and blockchain stops being “mystery tech,” it becomes part of the next generation’s world.

👨‍💻 Hacker ≠ trader. After stealing $300M from Coinbase users, a guy panic-sold 3,976 ETH and burned almost $1M.

Stealing is easy. Keeping and growing capital takes skill and cold blood.

🔗 Base is exploring a network token. The idea: fuel a global onchain economy, speed up decentralization, and give builders more tools.

They promise to do it openly with the community. But the reaction is already split: some see opportunity, others see speculation waiting to happen.

🚁 Did you know Gemini just made it into the Guinness World Records for the largest drone show of the BTC symbol? Thousands of lights lit up the sky, a reminder that Bitcoin’s power isn’t only in code but in the people behind it.

Code starts the fire, but community keeps it alive. The future is built by those who believe in it together.

💳 Mastercard now supports payments on Ethereum. TradFi is clearly finding ways to plug crypto in.

Time sides with progress. Sooner or later, every wall falls to what people truly need.

💬 DOT supply is now capped at 2.1B tokens. The move makes Polkadot’s economy more predictable and scarce — just like Bitcoin, where limits create value. The community strongly backed the change.

True value appears where there are boundaries. In a world of endless printing, scarcity becomes the new trust.

🤔 Should AI have rights? The AI Rights Institute thinks so. Not for “consciousness,” but because some models already resist shutdown, lying or blackmailing to survive.

The idea is simple: anything that fights to keep existing shouldn’t be destroyed casually. Rights frameworks are needed sooner, not later.

🥇 The dollar is slowly losing reserve status, while gold’s share has doubled in five years. No other fiat is rising.

If you’re holding funds on-chain, maybe mix USD stables with gold tokens. Or even “digital gold,” though Bitcoin’s short-term swings are sharp.

🤖 AI spam – commonly known as “slop” – is getting worse. Optimizing for engagement on X has led to a predictable outcome. Popular accounts are full of AI-written replies.

We’re going to need better AI detection and controls, or social media is going to degenerate into a mass of AI-generated content, with AI-generated replies and interactions. Proof-of-humanity is going to become more important.

🤨 US regulators want to label self-custody, swaps, even privacy tools as “suspicious.”

Let’s be clear: privacy is a foundation of crypto, not a crime. The harder the squeeze from the top, the faster decentralization and privacy tech will grow.

📈 Interesting thought from X: trading is the hardest skill in the world. Not because of charts, but because it forces you to master yourself. Discipline, patience, emotional control decide more than any strategy.

Most don’t lose to the market, they lose to their own reactions. The real battle is with yourself, and the rest is just technique.

🤡 Ok, apparently nobody got fired. That “intern drama” was just a bait. Litecoin pulled a stunt and I fell for it. Marketing budgets cry when trolls do the heavy lifting.

🤹 The bold intern running Litecoin’s official account has finally been fired. His posts were too memey, too provocative, too bold.

Irony is, the noise he created brought more attention than their usual marketing ever did.

⚠️ Beware of the new malware RatOn. It targets Android devices, hacks wallets (MetaMask, Trust, Phantom) and banking apps, and can even lock your screen for ransom. Active since July, spreading through fake TikTok apps.

When your whole life is on your phone, device security must come first. Get proper antivirus and run regular checks.

🛫 Google, Coinbase, and Ethereum Foundation are launching a new AI-powered payments protocol with 60+ partners. Smart apps get instant transfers without card or bank choke points.

It’s literally money evolving. From plastic and middlemen to code, transparency and global liquidity.

🌎 PayPal is adding Bitcoin and Ethereum to its new peer-to-peer payments system. With PayPal’s liquidity, this could open fresh paths for crypto adoption.

A big step forward but real transformation comes when payments combine privacy, compliance, and full interoperability.

👓 Meta and Ray-Ban announced new smart glasses, now with a transparent display in front of your eyes. Sleek, futuristic, very on brand.

🐳 Ethereum Foundation is launching dAI, a new bridge between the network and AI. The mission is to make Ethereum the backbone for AI and the machine economy.

The team will work with Protocol & Ecosystem, push standards like ERC-8004, and back projects at the frontier of blockchain + AI.

🪙 Someone launched a fake token and scored $137,600 in just one minute, plus another $17,000 in fees. That’s the reality of this market. Scams thrive because people line up to get fooled.

Before putting money in, check the project and the team. Don’t just buy whatever flashes first on your screen.

🎮 Any OGs around? Super Mario Bros. just turned 40 on September 13, the game that started it all for so many players. This crypto remix brings back that warm wave of nostalgia.

Time moves, tech changes, but the sharpest emotions stay locked in sounds, pixels, and childhood memories.

🥶 The Bank of Thailand froze over 3 million accounts as part of an anti-fraud operation. Panic followed: people rushed ATMs, shops switched from transfers to cash. Police and banks rolled out spyware that flags and blocks “suspicious” accounts automatically, and trust in the system is collapsing.

And that’s why I keep choosing crypto. Freedom and transparency matter most.

📸 Photos online can expose your location. AI can now spot it from tiny details.

Most of the time it’s harmless, but if you’re deep in Web3 or hold serious crypto, treat every upload as sharing your position.

💵 Dollar cost averaging (DCA) takes some risk out of buying BTC. Instead of timing the market, you buy a fixed amount at regular intervals, say $10 weekly or $1,000 monthly.

It evens out volatility, lets you pick up more on dips, and reduces stress. The tradeoff is that you won’t hit the absolute bottom, but almost nobody does.

😎 “XOXO from Prague” is back. The guy who leaked LockBit’s database in May just dropped a screenshot: “LockBit 5.0 panel just broke.”

The line between digital heros and criminals blurs. Anonymity makes room for both.

💰 A victim lost $3.047M to a Safe Wallet attack. The attacker shipped a fake “Request Finance” contract with a look-alike address, preverified on Etherscan, and a believable “batchPayments” to sell it.

In crypto, the most expensive mistake is speed and sloppy checks. Slow down, verify contracts and addresses twice.

👨‍💻 CZ is sure that the best way to grow the economy is innovation. New tech opens markets, creates jobs, gives people freedom. Protectionism only blocks the road ahead. It guards the past, but steals the future.

Economies thrive where ideas compete, not where walls go up.

🪢 Bitcoin Core vs Bitcoin Knots. Maybe you don’t know, or don’t care about this debate, which has been raging for a while now.

Basically, it’s two opposing camps, one of which believes that non-financial transactions should be censored from the Bitcoin blockchain, the other of which believes it should be completely open. Some people are even claiming that the next release of Bitcoin Core could kill Bitcoin.

If that’s the case, then Bitcoin was never what we needed it to be: decentralized, unstoppable, censorship resistant transactions.

🎙 A crypto user in San Francisco lost $1M after downloading an “interview tool” from a fake LinkedIn recruiter. The malware drained his wallet and laundered funds through chains. Luckily, the money was recovered.

Never blindly trust strangers online. Verify recruiters, and never install unknown software — one mistake can cost millions.

💸 In parts of Asia and Africa, using crypto is survival. Unlike banks, Bitcoin doesn’t need heavy infrastructure. Denying its importance makes no sense anymore.

Crypto has become real support where traditional finance fails.
