🎒 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.

🧠 Zircuit is launching Hyperliquid, an AI engine for real-time trading signals and cross-chain routing between EVM and Solana. Private beta drops end of July.

AI trading is going mainstream. Just hope we don’t read about its first hack by September.

😬 A cop’s bodycam accidentally caught a full Bitcoin seed phrase. Just a couple of seconds on pause, and it’s anyone’s wallet now.

Still writing your keys on crumpled paper? That’s not a backup, that’s an invitation to get robbed.

🕞 One of the most valuable things AI will give you is Time. As a search tool, it’s excellent at giving you the information you need quickly and in an easily-accessible form. The same information is available via Google, but it will take you much longer to find and understand it.

The question then becomes: What will you do with the time you have been given back? Modern life has a way of eating time if you let it, so be deliberate about how you use this “time dividend” of AI.

🕵️ Another on-chain takedown by ZachXBT. Crypto Beast shilled $ALT hard on X and Telegram, then dumped it on July 14 and wiped the promo posts.

Turns out he was tied to the wallets that sold the token. Lied to followers. Played the victim. And now account's deactivated.

🔗 "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.

🤯 Adaptability. Do you have it? It’s a critical skill to nurture in today’s fast-moving world. Technologies evolve. Markets rise and fall. Trends shift. Personal and national circumstances change.

⛏ 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.

🪙 Tether holds $8B in gold. Bitcoin may be “digital gold,” but the real thing still has a strong grip on big players.

🔑 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.

🤑 Owning 1 full Bitcoin is getting rare. Fewer than a million people have ever held 1 BTC or more, and that number won’t grow much.

With only 21M coins to exist, even a single BTC could be enough to future-proof your life.

🚀 Grok predicts Bitcoin will hit $1,000,000 by 2029. Sounds bullish, and crypto bros are hyped.

But markets aren’t just data. They’re chaos, panic, and politics. Get inspired, just don’t invest like a chatbot.

😐 James Wynn is back with a 256 BTC bet on Bitcoin hitting $120K. But we’ve all seen this movie before.

Crypto X is already joking: BTC won’t go up until Wynn gets liquidated again. He’s nearly there: margin call knocking at $118K.
