Montanha Bitcoin

It’s a powerful incentive for merchants in a circular #Bitcoin economy when Bitcoiners keep spending sats even during bearish cycles. When we keep transacting regardless of price, we prove that real adoption is built through daily use, trust, and long-term vision.

Bitcoin Circular Economy on @satsconf_ @btcmap #SPEDN

The perfect bus to go to @satsconf_ , real school for many of us, including 11 young guys from our comunity that experience thia amazing Conference. Thanks everyone in special @BitcoinConfed , @uaibit , @fraguismo , @montanhabitcoin and @BitcoinBeachBR for this couple days..

Tivemos a honra e o prazer de conhecer essa cidade maravilhosa e abençoada que é São Thome! • @montanhabitcoin feito com muita dedicação pelo @mestreleiva entrega muito mais do que números, entrega educação real! Aqui, os comerciantes não só aceitam bitcoin, eles entenderam o conceito de moeda fraca e moeda forte! Vamos seguir trazendo exemplos de histórias e pessoas pelo Brasil e mundo a fora que já entenderam que o dinheiro e o estado na mesma linha não rimam! Se quiser acompanhar essa jornada de perto com a gente, é só comentar CABULOSO que eu te envio o link do grupo no whats Estamos sempre postando os bastidores por lá! Salve Sua Família, Estude Bitcoin.

Foi lançado a versão em português do livro sobre as economias circulares de #Bitcoin a.co/d/4F3Xf58

Veja como foi o quarto aniversário do experimento Praia Bitcoin Jericoacoara Graças a @Bitcoinize, @BitcoinConfed e @BitcoinBeach foram distribuídos mais de 50 cartões de débito de Bitcoin via Lightning, o @bolt_card, carregados com 10 mil sats cada. Contamos com a presença da @usebipa, que entendeu como estamos fazendo a Bitcoinização de Jeri e o quanto pode ajudar em nossa missão, desenvolvendo a integração com o @BtcPayServer Muito obrigado a todos!

We're preparing something exceptional for @satsconf_. Praia +4 Bitcoin circular economy projects: @MontanhaBitcoin, @bitcoineaqui, @bitcoinamantiki, @Bitcoin_Forte, and the “Enjoy Being Free Movement” mural. The @BitcoinConfed stand will feature @Bitcoinize Machines, printing personalized @bolt_card for visitors, aiming to break the Las Vegas 2025 Bitcoin payment world record. @uaibit will onboard visitors (lightning/on-chain), and we're organizing a store with products from circular economies, accepting only Bitcoin payments. All operations are 100% paid in BTC—no fiat, just peaceful money!

Galera do Ceará, mais um evento do @MotoleseOficial e da galera da Praia Bitcoin em Jeri.

The community keeps growing under the #Bitcoin standard, and day by day, more and more people are getting “bitten by the orange bug.

After a 7-hour journey copying the entire blockchain onto a new drive, the Montanha Bitcoin full #bitcoin and lightning node is now running at full power. ⚡️

Another event delivered together with @bitcoinbeachbr, it was 15 days of hard work and learning about circular economy, bitcoin payment infrastructure, music production, and much more. Happy to be part of this history. Let the sats flow… #bitcoin

Updating the node storage since 1TB is no longer enough to store the #bitcoin blockchain 😎

🚀 Thrilled to share that I’ve written a special article for @BitcoinMagazine: “A Circular Economy and the Four Archetypes of Bitcoiners” A deep dive into the intersections of culture, politics, and technology 👇Read it here bitcoinmagazine.com/culture/bitcoi…

The work goes on, and over 50 new personalized cards have already been printed for the children of the @bitcoinbeachbr project. Peaceful revolution, financial inclusion for the unbanked.

Hello @bitcoincoreorg, We live Bitcoin. We dedicate our lives to it, full time, nonstop. On the ground, we work as part of Bitcoin’s invisible team, often without salaries, simply because we believe in its power to fix money and defend society from injustice and authoritarianism. Bitcoin is beautiful. But it can also become fragile, outdated, or even corrupted, if we do not care for it with the seriousness it deserves. The white paper begins with the words: “Bitcoin: A Peer-to-Peer Electronic Cash System.” Not a decentralized database. That distinction matters. Developers must lower their time preference and think in terms of centuries, not release cycles. Bitcoin is a cash system designed for global adoption in commerce. That was Satoshi’s vision. Originally, in 2014 Bitcoin Core introduced OP_RETURN with a 40-byte limit. In 2015 this was raised to 80 bytes, and in 2016 clarified as an 83-byte script length. For nearly a decade the rule stayed unchanged. Then, in 2024 with Core v29, the policy was relaxed to allow multiple OP_RETURN outputs per transaction, although each remained capped at 80 bytes. Now, with Core v30 (2025), the long-standing cap itself has been removed entirely: OP_RETURN outputs are no longer bound to 80 bytes, and multiple OP_RETURNs per transaction are allowed, bounded only by general transaction-weight (~100,000 vbytes) and block-weight (4 MB) limits. This is extremely risky. By first allowing multiple OP_RETURNs (v29) and now eliminating the explicit size cap (v30), Core normalizes and facilitates behavior that was once discouraged. It opens the door to spam, bloat, and malicious use cases. It allows attackers to inject unwanted or even illegal content directly on-chain, potentially exposing node operators to liability. Users should have the freedom to filter what they host, but Core should not encourage practices that turn Bitcoin into a data-storage network. Yes, arbitrary data can already be forced onto the blockchain in different ways. But these policy changes transform a fringe misuse into a legitimized practice, encouraging precisely the kind of abuse that poses systemic risks. A public-opinion crisis, triggered by toxic or illegal content, could cause catastrophic damage to adoption and market confidence. Bitcoin is money. Just as you can scribble a short note on a banknote but not publish a book on it, Bitcoin transactions can carry limited messages but should not be hijacked for unrelated purposes. If protocol development drifts toward use cases that weaken Bitcoin as cash, the consequences will be severe. The network is already signaling concern: voices like @BitcoinKnots resonate because Bitcoiners are smart, technical, and willing to act when needed to protect the network. We have already built important advancements to secure Bitcoin’s long-term future. Let us not undo this progress. Let us stay true to the vision: Bitcoin as a peer-to-peer electronic cash system.
