Bitcoin y amigos Esa es la felicidad.

La aversión de muchas personas a Saylor es interesante. Esperan que fracase. A mi me da igual. Lo que llama la atención es que las mismas personas que te hablan de libertad y bitcoinización para todos son los mismos que escupen a las mismas corporaciones que deberían adoptar bitcoin. Que tus ideales no choquen con la realidad, que ambos se adapten es la cuestión.

AI won't replace many things. People who owns bitcoin is one step ahead but you need more capital. Your brain is your capital, take care of it. In this article, based on McCormack's podcast, I give you some tips. View article →

Reading Edward Gibbon on the *Fall of the Roman Empire*, I can’t shake the feeling that this is not really history. It feels more like a manual. What strikes me the most is how familiar the symptoms are. Different names, different eras, same underlying patterns. It’s as if empires don’t collapse randomly — they follow a script. Right now I’m reading about the Roman economy: currency debasement, rising pressure on production, and a system that needed constant expansion just to sustain itself. That alone feels uncomfortably close to how modern systems operate. Growth is no longer a goal; it becomes a requirement for survival. Then there’s the mercenarization of the army. Rome moved from citizens defending their own system to hiring outsiders with no real attachment to it. That shift matters more than it seems. When the people maintaining a system no longer believe in it, or have no stake in it, the system becomes fragile, even if it still looks strong from the outside. But the concept that really stayed with me is overgrazing. A biological term, simple but brutal: when consumption outpaces regeneration, collapse becomes inevitable. It’s not immediate, but it’s already set in motion. Applied beyond biology, it’s hard not to see parallels. Economies, institutions, even cultures can enter that phase — extracting more than they can rebuild. What Gibbon describes doesn’t feel like a unique event in history. It feels like a pattern. And maybe the real question is not why Rome fell, but **how many systems today are quietly following the same path**.

There's something called "1984 index" which give us some sense about people who don't trust the system. My latest article for NOSTR View article →

Pavel Durov esta muy activo ultimamente y eso me preocupa. Es un hombre que ha declarado cientas de veces que no tiene celular y solo vive de la actualización de Telegram pero su modo defensor de la privacidad (la cual apoyo) me tiene preocupado porque en las ultimas semanas, ha estado mas activo que en los últimos siete años. ¿Que me estoy perdiendo?

Leer este ensayo te hace comprender que los musulmanes y cristianos no tienen ninguna diferencia en el objetivo a ser alcanzado, al plan divino y cientas de cosas que mientras leía, decía para mi mismo "esto es prácticamente replicable en el cristianismo", por lo que el Hijra Digital termina siendo como una suerte de cristianismo responsable. Recomendado que se tomen el tiempo y lo lean detenidamente. View article →

Cuando entiendan que el comunismo fue la idea de unir a la clase baja y clase media contra la oligarquía explotadora y que el mismo es un producto directo del capitalismo, ese día...cerebros explotarán.

The international landscape is showing us many things at once. One of the most striking observations in recent days is how symbols of power are beginning to look fragile. The USS Ford, once perceived as an intimidating war machine, now feels more like a paper boat in a storm. The United States warns about a war that, deep down, it knows it cannot fully win, while Iran appears more than ready to confront whatever comes its way. Today, the United States is putting its global hierarchy at risk for a state that, paradoxically, does not fully align with it and may even reject it in the long run. It is being used, in many ways, as a puppet under the label of “ally.” The idea of a “Greater Israel” does not include many of those who currently support it, including Christian Zionists who are fighting for a cause they may not fully understand. History has shown us similar patterns before. Knowledge transfers, shifting alliances, and misunderstood motivations have shaped entire civilizations—just as they did centuries ago between early Islamic expansion and Jewish communities. From this perspective, several possible scenarios emerge. First, Israel seeks to consolidate itself as a dominant regional power and will continue to leverage the military strength of the United States until that strength becomes unsustainable. There will come a point where the U.S. can no longer maintain its presence and will be forced to withdraw its naval and military bases. When that vacuum appears, the real question is: who will fill it? Which country has both the technological capacity and human capital to step in? The answer may not be surprising. Second, despite appearances, Iran and Israel are not necessarily engaged in a purely bilateral conflict. If we analyze the map and the dynamics, this is fundamentally Iran versus the United States. Israel acts more like a trigger—initiating tensions and then calling in its stronger ally. The Persian legacy and geopolitical ambitions of Iran do not align with the concept of a “Greater Israel,” but neither are they as isolated from broader strategic alignments as many believe. Third, the emerging powers in the region are likely to be Israel, Saudi Arabia, and Iran. As global structures weaken and rebalance, these actors will gain relevance. In that context, the U.S. dollar, already showing signs of strain, will increasingly be questioned. However, questioning a system does not mean replacing it. This is where a critical misunderstanding lies. Many point out the weakness of the U.S. dollar, and they are not wrong. But what is often overlooked is the absence of a viable alternative. China is not interested in assuming the role of global reserve issuer. India, Brazil, Russia, and others have expressed intentions to move away from dollar dependency, yet none of them offer a coherent replacement system. It is not enough to reject a currency; a functional alternative must exist—and today, it does not. In this environment, uncertainty dominates. For some, the response is faith; for others, reflection. But for a growing number of people, the response is Bitcoin. The Strait of Hormuz becomes a perfect geopolitical excuse, a pressure point where global trade, energy flows, and military tension intersect. In that context, Bitcoin is increasingly mentioned as a potential alternative. However, realistically, it is difficult to imagine states actively promoting a system they cannot control—especially in such sensitive geopolitical scenarios. Still, the fact that Bitcoin is even part of the conversation is remarkable. It reflects a deeper shift: not necessarily in state behavior, but in individual awareness. Whether or not it becomes a true alternative in the short term, the mere presence of Bitcoin in these discussions signals that the current system is no longer unquestioned. And that, in itself, is already a change

En la playa aprendiendo sobre las diferentes épocas de los desarrolladores de bitcoin core y su impacto en cada época, escrito de un modo sutil. Gracias @Mintoshi por el aguante, hoy te digo que en este lugar hice clic de muchos BIPs que actualmente existen. image

En Paraguay, algo que saltó las alarmas de muchas personas fue la Resolución 47 de la DNIT donde se estipula algunas cuestiones de propósito tributario. No se crea impuestos, aclaro pero cambiaron las reglas del juego. Con @Bitcoin Paraguay y @Jan Kotas y Eduardo Hillar hablamos de ello. Mientras más avanzaba la charla, mayor era al sorpresa de las personas asistentes, quienes vieron la verdadera cara de lo que esto implica. Así que...hay mucha tela por cortar. image
