The banking system keeps surprising me. Turns out you can't initiate an international transfer that takes 3 days to arrive over the weekend, because the forex market doesn't operate on weekends. Bitcoin fixes this.

Excellent presentation by Pamela Morgan from 9 years ago. Still just as valid and useful as on day one.

Bitcoin in Real Life II My wife studied artisanal jewellery design and worked for several years crafting unique pieces. Yesterday, someone from her hometown messaged her asking if they could call her for a quick consultation. The situation? Her mother-in-law had recently passed away, leaving behind a large collection of jewels. Over the years, she had purchased these pieces during trips to places like India, Africa, Brazil, and Mexico. Some featured precious stones, others were made of gold or silver. It was a diverse and valuable collection. She didn’t buy them just for beauty, she saw them as a form of savings, a way to preserve value over time and even move wealth across borders if needed. And honestly, that made perfect sense. For generations, saving in gold and jewels was one of the most practical ways to store value, especially for those who didn’t fully trust banks or wanted something physical they could take with them in uncertain times. But since 2009, we have a tool that allows us to do this in a much simpler, safer, and more efficient way: Bitcoin. Now, the family wants to divide the jewels into eight lots of similar value to distribute among the heirs. My wife’s answer was straightforward: Most jewelry is valued by the weight of the metal, gold or silver and the quality of the stones. The craftsmanship rarely adds much to the resale price unless it comes from a known designer or brand. Her advice: visit multiple jewelry shops, get a few appraisals, and use those estimates to create balanced lots. But just imagine… If instead of jewels, this woman had left Bitcoin. There’d be no need for appraisers. No arguments over who gets what. No guessing, no expert needed to evaluate the worth or certify the authenticity. Just a universally recognized, mathematically verifiable asset that can be divided down to the smallest unit and distributed with perfect fairness. BTC fixes this.

Bitcoin in Real Life Last week I went on a very special trip: a family reunion. As many of you know, I’m originally from Venezuela, and we all planned to meet up in Spain. Family came in from the U.S., Costa Rica, Australia… and of course, from Venezuela. For someone still living in Venezuela, getting access to foreign currency is incredibly difficult. Some have managed to open bank accounts abroad to keep part of their savings in a currency that doesn’t lose value as fast as the bolívar. One of my relatives, a long-time CitiBank customer, had never had issues with his bank—until now. While vacationing in Spain, his account was suddenly frozen. Just like that, he couldn’t use his debit or credit cards. When he contacted the bank, they told him he’d have to physically go to a Citi branch in the U.S. to unlock his account. I gave him a simple but powerful suggestion: next time he travels, he should carry a Bitcoin wallet with some funds. I explained that with just that, he could access local currency anywhere in the world—no banks involved. He didn’t know there are Bitcoin ATMs in Spain. I showed him how the lnp2pBot on Telegram works, and he was surprised by how many people were ready to buy Bitcoin instantly. I also showed him the map on btcmap.org, where he could see all the businesses that accept BTC as payment. That really opened his eyes. I’m sure that now he sees Bitcoin differently—not just as an investment asset, but as real money. BTC fixes this. That simple.
