One day left until two years before the Bitcoin halving.

AI agents shouldn't get the full key to your kingdom. Today we're releasing Nunchuk CLI: create a shared Bitcoin wallet with your agent, give it a spending budget, and keep the final say. Build Bitcoin agents with bounded authority.

@Mark_MNLocal Some of the products are only available to residents. Most that interface with banks do stable coins and not btc.

Does anyone have a suggestion for what app or service would be best for use in Mexico for sending/receiving bitcoin?

BREASTMILK She thought she was studying milk. What she uncovered was a conversation. In 2008, evolutionary anthropologist Katie Hinde was working in a primate research lab in California, analyzing breast milk from rhesus macaque mothers. She had hundreds of samples and thousands of data points. Everything looked ordinary—until one pattern refused to go away. Mothers raising sons produced milk richer in fat and protein. Mothers raising daughters produced a larger volume with different nutrient balances. It was consistent. Repeatable. And deeply uncomfortable for the scientific consensus. Colleagues suggested error. Noise. Statistical coincidence. But Katie trusted the data. And the data pointed to a radical idea. Milk is not just nutrition. It is information. For decades, biology treated breast milk as simple fuel. Calories in. Growth out. But if milk were only calories, why would it change depending on the sex of the baby? Katie kept digging. Across more than 250 mothers and over 700 sampling events, the story grew more complex. Younger, first-time mothers produced milk with fewer calories but significantly higher levels of cortisol—the stress hormone. The babies who drank it grew faster. They were also more alert, more cautious, more anxious. Milk wasn’t just building bodies. It was shaping behavior. Then came the discovery that changed everything. When a baby nurses, microscopic amounts of saliva flow back into the breast. That saliva carries biological signals about the infant’s immune system. If the baby is getting sick, the mother’s body detects it. Within hours, the milk changes. White blood cells surge. Macrophages multiply. Targeted antibodies appear. When the baby recovers, the milk returns to baseline. This was not coincidence. It was call and response. A biological dialogue refined over millions of years. Invisible—until someone thought to listen. As Katie reviewed existing research, she noticed something unsettling. There were twice as many scientific studies on erectile dysfunction as on breast milk composition. The first food every human consumes. The substance that shaped our species. Largely ignored. So she did something bold. She launched a blog with a deliberately provocative name: Mammals Suck Milk. It exploded. Over a million readers in its first year. Parents. Doctors. Scientists. People asking questions research had skipped. The discoveries kept coming. Milk changes by time of day. Foremilk differs from hindmilk. Human milk contains over 200 oligosaccharides babies can’t digest—because they exist to feed beneficial gut bacteria. Every mother’s milk is biologically unique. In 2017, Katie brought this work to a TED stage. In 2020, it reached a global audience through Netflix’s Babies. Today, at Arizona State University’s Comparative Lactation Lab, she continues reshaping how medicine understands infant development, neonatal care, formula design, and public health. The implications are staggering. Milk has been evolving for more than 200 million years—longer than dinosaurs walked the Earth. What we once dismissed as simple nourishment is one of the most sophisticated communication systems biology has ever produced. Katie Hinde didn’t just study milk. She revealed that nourishment is intelligence. A living, responsive system shaping who we become before we ever speak. All because one scientist refused to accept that half the story was “measurement error.” Sometimes the biggest revolutions begin by listening to what everyone else ignores.

The Bitcoin Standard by @saifedean explained in 2018 how the current Silver rally will inevitably end.

A perspective on the absurdity of Strategy using trusted third parties to custody their BTC: For the cost of a single weekly BTC purchase ($XXXM), they could afford to buy any of a number of companies that specialize in bitcoin custody, thus pulling the expertise in-house.

@theRealKiyosaki Probably opted not to sell silver just because it’s harder to sell?

FYI SILVER Fact: I was at VRIC Vancouver Resource Investor Conference. Great event for anyone serious about their financial education on gold and silver. At VRIC I was informed there is a rumor I sold all my silver to buy more Bitcoin. This is not true. The facts are: I sold some Bitcoin and some later some gold to buy my new home. I have not sold any of my silver. I wish I had not sold some gold and some Bitcoin. Selling some gold and Bitcoin was my mistake ….a big mistake. Thank God I did not sell my silver. Why sell silver, when I use debt to buy investment real estate for positive cash flow with which I buy more gold, silver, Bitcoin, and Ethereum. Take care. Great time to sell fake dollars to buy real gold, silver, Bitcoin, and Ethereum . Take care

@MichaelRosmer There is no digital scarcity in blockchain. Cryptocurrencies are infinite. Bitcoin has digital scarcity.

In a world of AI where code is virtually free does Blockchain become valuable because of digital scarcity? Alternative view is networks become fungible infrastructure in the background abstracted away

@NickGuthre To keep him healthy for the Superbowl. He hasn't made it deep in many seasons.

Kenneth Walker in 2 games as the workhorse: 259 Total Yards and 4TD's (and counting) Can't fathom why they kept giving Charb the bulk during the regular season when you have a guy like this.

Pretty sad to see this issue hit so close to home. I’m a graduate of Emerald Ridge HS. The Democratic Party must divorce the idea that trans athletes should compete in girls sports before they can win another presidential election.

@bp22 Playing the lottery is a low IQ activity. Why are you surprised?

I can't even .....

Noticing from an albeit small sample size that Canadians are broke and resorting to unethical business practices (scamming). Real estate values in Canada and their currency are not doing well.

The romanticism here is beautiful, but the math isn’t. Reality check on “grass-fed”: ∙Only about 4% of US beef sales are grass-fed, and less than 1% of cattle slaughtered are 100% grass-finished ∙75-80% of “grass-fed beef” sold in the US is actually imported from Australia, New Zealand, and South America ∙~95% of US cattle spend their final 4-6 months in feedlots eating grain-heavy rations (70-90% grain/concentrates) What feedlot cattle actually eat: Corn (primary), soybean meal, soybean hulls, corn silage, distillers grains, cottonseed, barley – plus antibiotics and growth hormones. Yes, the same soy you’re criticizing. The irony: You mock flying in soy from Brazil while the conventional beef industry is one of the largest consumers of Brazilian soy. The US cattle industry uses massive amounts of soy-based protein supplements in feedlot rations. The cow IS an amazing biological system. But pretending the industrial beef system is just “cows eating grass” is the real fantasy. The bucolic image you’re painting exists for less than 5% of beef production. Want to make the “grass-fed” argument? Great – then advocate for actually transitioning to that system instead of defending the industrial one with pastoral poetry.

Low-frequency electromagnetic fields can degrade collagen, weaken tendons, and cause soft-tissue damage at levels regulators call "safe." We have a real world case study proving this: An NFL team whose practice facility sits next to a massive electrical substation. THREAD 🧵 peteranthonycowan.substack.com/p/could-chroni…

On January 7th 2023 exactly three years ago today Bitcoin was worth $16,950.

I personally think it’s hilarious that thousands of the world’s most brilliant PhDs devote their lives to perfecting hedge fund algorithms, only to severely underperform Bitcoin.

Almost became US Vice President. Political career ended by a 23 year old independent journalist with a video camera and a social media account. If you need an example as to why social media must be protected from govt control this is as good a place to start as any.
