🖕 Brian Armstrong brought back Satoshi’s old line from 2010. Basically, if you don’t get it, that’s your problem. Back then, Bitcoin was just noise to most people. Today, hundreds of millions understand the signal.

No need to explain it anymore. Time did the work.

💆‍♂️ Robots now give massages. Tap the screen, and two mechanical arms get to work. Forget that awkward small talk and judgy looks, enjoy consistent pressure and peace.

Finally, a massage without the human drama.

🪙 Ethereum’s been running 10 years straight with zero downtime and no maintenance windows. While Web2 giants pause for upgrades and rely on support teams, Ethereum kept going through forks, crashes, bubbles, lawsuits, hacks, and wars.

Not because of a CEO or customer service, but because millions of devs, stakers, researchers, and users keep pushing it forward.

💰 Bought a hardware wallet from a shady seller, lost 4.35 BTC. Seed phrase was pre-set and known to the scammer. As soon as the funds landed, they were gone.

Tried to save a few hundred, lost over half a mil. That’s what cutting corners on security looks like.

😡 25 years ago, Chancellor Gordon Brown sold the UK’s gold reserves. He offloaded 395 tonnes at an average price of around $275 per Troy ounce, generating around $3.5 billion.

It was a terrible financial move. That gold would now be worth almost $43 billion.

Unfortunately, Chancellor Rachel Reeves is now thinking of selling the UK’s reserves of seized bitcoins, which would net the country around $6.7 billion. I think we know how this story ends.

🎒 Students from El Salvador just wrapped up their Bitcoin Summer School in Lugano, Switzerland. Honestly, it still surprises me, the first country seriously investing in its next generation through crypto.

While the rest of the world argues over regulation, El Salvador is training the next wave of Bitcoin talent. That’s how you lead.

🪙 Vitalik laid out his vision for making Ethereum great again: mass adoption without sacrificing security or decentralization. He admitted that in the past, DeFi was too risky to recommend as a savings tool for everyday users. But now, losses from hacks are down to just 0.53%.

Ethereum’s moving forward with confidence, and it looks like the future of blockchain is in capable hands.

🤪 The marathon of AI-generated madness continues. Grok just shared a new one: Bitcoin hitting $25,000,000 by 2046.

At this rate, we’ll be quoting BTC prices in national budgets and trading coins for small countries.

💼 If you’re buying and selling crypto, you’ll almost certainly need to take tax into account these days.

That’s unless you happen to be in one of a very few jurisdictions that have very favorable tax treatment with holders sometimes being required to pay nothing at all!

The Cayman Islands and UAE are two examples. Germany and Portugal are also on the list for long-term holders – but ALWAYS make sure you check and understand the rules so you don’t get caught out.

🤖 A while back I mentioned Moravec's Paradox. This states that tasks humans find easy, like perception, motor skills, or common-sense reasoning, are often difficult for AI to perform. However, many tasks humans find hard, like complex calculations or logical analysis, are relatively easy for AI.

Well, no one told this velociraptor-style robot. It has an AI-powered tail for balance, and can run at 46 km/h (almost 30 mph).

In the robot uprising, your best chance may be to hide in a tree…

👾 And now, apparently, Bitcoin miners are moving into AI. Following last year’s Halving and the drop in block rewards, some miners began to struggle to make ends meet.

They diversified, using their data centers and GPUs to power cloud-based AI compute operations.

Now, AI is a parallel revenue stream for an increasing number of miners. For example, 9% of Hive’s revenue came from AI and High Performance Computing (HPC), with the rest coming from Bitcoin mining.

💰 WOO X was hacked for $14M after a phishing attack compromised one employee’s device. 9 accounts affected, full refunds promised. Trading and user funds are safe.

Security is a constant priority. One compromised device can take down the whole system.

💀 The CEO of CryptoQuant just said it straight: the Bitcoin cycle theory is dead. Whale behavior no longer predicts the market. BTC is moving to long-term institutional hands, not retail.

Admitting you're wrong means you're adapting. And once again, making predictions in crypto is a waste of time.

🇹🇭 Thailand’s turning into a serious playground for Web3, AI, and sustainable tech.

Here’s one event that’s worth showing up for:
Synergy Forum 3.0 in Phuket talks on human potential in the AI era, decentralized infra, and legaltech that works. If you're in Thailand, save the date.

🗓 Nov 28–29 @ BTC Space, Phuket

☠️ Most people put off crypto inheritance planning until it’s too late. If you actually want your kids to access your assets one day, you need to set it up while you still can. Cointelegraph just dropped a useful guide.

Being prepared isn’t paranoia. It’s care.

💋 Someone has vibe coded a game based on that viral Coldplay concert moment. It’s called Coldplay Canoodlers. You have to find the CEO and HR lady together in the vast crowd, earning 10 points every time you do so.

It’s a frivolous use of AI, but it demonstrates how powerful vibe coding (using AI to write software, without any coding skills) can be.

Previously, people would just create a meme around such a viral moment. Now, you can throw together a game. What next?!

🪙 Ray Dalio now says 15% of your portfolio should go into Bitcoin. Not long ago, he was saying 1%.

😰 Wanna hear about a trader with ice in his veins? He shorted ETH on June 11 right at peak FOMO, price crashed from $2880 to $2120. Yesterday he did it again, shorting just after $3940 got rejected.

Timing like that isn’t luck. That’s nerves of steel and serious skill.

📱 PayPal just made a real move toward mainstream crypto adoption. US merchants can now accept 100+ coins: from Bitcoin to Solana meme tokens. Lower international fees too, since transfers can go through crypto.

That’s how fintech giants quietly build the new economy.

⚠️ Warning: fake accounts are now impersonating major crypto channels like Watcher.Guru and spreading false news. Some users have already fallen for it.

In crypto, panic from fake news can spread faster than the Bitcoin price. Stay sharp: block, report, and double-check your sources.

🔗 "There are so many opportunities, so much to build." CZ said it simply, but that’s the whole truth of the time we live in. Blockchain is a construction site. Everyone’s holding a brick of the future: code, idea, community, or capital.

Tech has cleared the fog. Yesterday’s unknowns are today’s open doors. The only question left is who’s bold enough to walk through.

🤫 Sam Altman reminded everyone of an uncomfortable truth: ChatGPT is not your friend. Millions share their secrets with it, not realizing that this data can be used as court evidence. Altman himself calls it “deeply wrong” and urges stronger protection measures.

AI listens well, but it doesn’t keep secrets. Think twice before you get personal.

🗞 Where do you get your news? Mainstream news sites? X/Twitter? YouTube? What about crypto news? The crypto media? X/Twitter? Or mainstream sites?

X is good for breaking news, especially in crypto, but be careful of the “narratives” the algorithm feeds you. The main thing is to verify everything before acting on it.

😎 Using privacy tools like Tornado Cash isn’t illegal, but it can get your account flagged by exchanges.

Instead, practice good wallet hygiene. Withdraw large purchases to a fresh address with no link to your main account. Stay private, stay safe.

⛏ UK gold mining firm Nativo Resources is building a Bitcoin reserve. They're not just buying BTC, but tying their balance sheet to it.

When people who understand scarcity choose digital gold, it's a sign that value is being redefined.

🤪 James Wynn is calling for crashes: Bitcoin to $113K, ETH to $3K, alts into the abyss. But we all know which falls are actually worth watching.

🔑 Bitcoin lending is a growing theme this cycle. Holders can use BTC as collateral to borrow money. There are even Bitcoin mortgages available!

It’s a nice idea, in theory. Instead of selling, and losing exposure to those coins (as well as incurring capital gains), you can just borrow against your BTC.

The catch is that you lose custody of your collateral. Remember: Not your keys, not your coins.
