It featured voices from Spain, Venezuela, Mexico, El Salvador, Argentina and other Hispanic countries
The truth is not within an individual person, but is born between people, in the process of their dialogic interaction.

TO Watch Out! Bitcoin He leaves to exercise his thinking and to learn how to act accordingly. If you are mentally lazy or prefer to have your ideas chewed up and regurgitated by an artificial intelligence, this is not the event for you. The format of the conference, which privileges debate and workshops over monologues, demands that thought be put into play and subjected to replications, but also that it be put into action, offering the necessary tools to build, with technologies of freedom, a more responsible and sovereign life. At least that was our impression of the fourth edition of the event Bitcoin Only most important in Spain.
To make brick, you have to put your hands in the clay. Under this premise, the first day of the event, Friday, October 3, began by offering attendees experiential knowledge: workshops on topics as varied as mining, Nostr, bitcoin heritage, investment, decentralized finance. Even making room for those who are just starting out in the ecosystem, an introductory Bitcoin workshop aimed at all ages. The only bad thing: all the workshops coincided in time, so we had to choose wisely where our interests best aligned.
This opportunity cost dissipated during Saturday and Sunday, when all the debates were concentrated in the same room.
This 2025, the Bitcoin industry and players have changed in ways that few would have expected a few years ago. States and institutions of the fiat world increasingly have a greater presence and participation in the ecosystem. Under this panorama, the debates of Watch Out! Bitcoin 2025 They started with the question Where is the Power? The answer, at least for speakers like Felipe Huicochea from CriptomonedasTV, is in the nodes. Although new actors enter and amass significant amounts of BTC, in the end it is the users who run the Bitcoin software who validate the rules and They ensure that any attempt at arbitrary change is innocuous and impotent. It all depends on consensus.


But that consensus is one of the most difficult things to achieve in a system where relationships are horizontal and no one imposes themselves on others, is something that the debate on Ethics, Economics and Investment in Bitcoin. To prevent the mistake of being locked in an echo chamber, surrounded by people who only validate our biases and assumptions, it is important to invite people like investor Daniel Baeza to the debate.
Baeza reminded us that there are people who prioritize returns over self-custody, which is not something morally reprehensible. As long as, as the analyst Juan Rodríguez objected, one is aware that the characteristics of sovereignty are being wastedbecause it offers to have full control over the private keys. But, in the end, purity tests or the bitcoiner card, as Lunaticoin called it, usually drive away people who could benefit from bitcoin under their own strategy.


However, there are exclusions and censures that are not a consequence of the call toxic maximalism. Following the arrest of the developers of Samourai Wallet and Tornado Cash, developers are self-censoring when it comes to implementing privacy tools in their products.
This is what Ben Kauffman, developer of the Bitcoin Keeper wallet, considers, who commented that, despite the regulatory change resulting from the election of Donald Trump as president of the United States, There remains an abstention among his colleagues to prevent future persecutions.
Given this panorama, privacy specialist Arkad replied: if developers do not provide the tools, what measures are left for users? He himself responds that at least the Ashigaru fork took Samourai’s baton to continue in the race for privacy, and developer Sergi Delgado added that the implementation of Silent Payments will also provide more on-chain privacy for users.


The desire for financial privacy does not clash with the need for greater physical gatherings to discuss and educate about Bitcoin. In the discussion on communities it became clear how different organizing meetups can be depending on the context. While for the author of Criptoria, Alfre Mancera, Spanish institutions allow for requesting access to public spaces such as administrative premises that are underutilized to be able to disseminate information about Bitcoin, and for the co-founder of Bitcoineta EU, Ariel Aguilar, having a fixed establishment such as Espacio Bitcoin was key to the education of Argentine bitcoiners, panoramas such as the Venezuelan one were not so kind to the founder of Satoshi in Venezuela, Javier Bastardo, who stopped organizing meetings to safeguard the integrity of the attendees.
The founder of Bitdriver, Napoleón Osorio, even says that if El Salvador had not become safe, he would have left the country after someone spread a deep fake created with artificial intelligence where he was simulated saying that he had become a millionaire thanks to Bitcoin.


And artificial intelligence is presenting both opportunities and challenges in all areas, and Bitcoin is no exception. From the perspective of cybersecurity expert Gonzalo Álvarez Marañón, the increase in productivity in software development thanks to the use of AI will make technology advance by leaps and bounds. It is not long before AI agents manage bitcoin wallets and automate payments transparently for users.
This advance does not come without ethical dilemmas, as raised by Bastardo, which vindicates the role of philosophers to demarcate a path that puts humans at the center of development to avoid technological dystopias. For Álvarez Marañón, however, the real dangers do not come from hitman drones paid by AI agents with bitcoin, but from collapse of Democracy because it is impossible to distinguish what is true from what is false. In that scenario, not only will there be greater manipulation of public opinion as there is now, but the evidence in trials will be practically useless.


Watch Out! Bitcoin 2025 It gave rise to the meeting of a multiplicity of reflections, sometimes shared, sometimes in conflict, but which remind us how varied and multidisciplinary Bitcoin is. In a protocol without owners or leaders, which is built by the meeting of multiple and uncoordinated desires and wills, there is no other choice but for thought to emerge in this dialogic way. This conference left us wanting to know more, but above all about debate more, to have more face-to-face meetings with bitcoiners. At a historical moment where artificial intelligence threatens to atrophy thinking, Watch Out! Bitcoin It calls us to preserve it.
