. Key Takeaways

  • Bruno Oliveira is on a journey to show how small, steady actions can embody Bitcoin’s Proof-0f-Work in real life.
  • Once mocked by friends, he’s now recognized globally for his mission to accumulate as much Bitcoin as possible.
  • After discovering the power of crypto, Oliveira now wants to inspire the younger generation.

When Bruno Oliveira began collecting discarded aluminum cans to buy Bitcoin (BTC) after losing all his savings, some of his friends in his hometown of Limeira laughed at him about his new obsession.

Two years later, he’s gone viral for his mission and is even writing a children’s book to inspire the younger generation.

Lost Savings, New Beginnings

Oliveira, who goes by the nickname ‘Sucateiro Cripto,’ meaning “Crypto Scrap Dealer,” began his recycling project in 2022 after the COVID-19 pandemic wiped out much of his savings.

Faced with unemployment and limited resources, he decided to try to turn his project into an opportunity.

“What inspired me was the lack of resources during the pandemic,” he told CCN.

“I had to use all my investments, but the desire to keep going remained,” he added. “That’s when I came up with the idea of recycling cans.”

Even though it wasn’t much, Oliveira realized that what truly mattered was to keep “a reserve in Bitcoin and to never give up.”

Saving Cans For Bitcoin

Working mainly on weekends, Oliveira collects discarded aluminium cans from the streets of Limeira and nearby neighborhoods, selling them to local recycling centers and converting the proceeds into Bitcoin.

The process, he says, is slow but symbolic, proof that even small, consistent efforts can build something meaningful over time.

“What matters is taking the first step and understanding that even small amounts can become valuable,” he added.

Oliveira earns around 20 to 30 reais ($4–6) per weekend from recycling, modest by any standard, which he converts directly into Bitcoin.

“Reaching 1 BTC through recycling alone is really impossible,” he said.

“But I try to show people that any percentage can make a difference. My goal is to reach 0.1 BTC by recycling mainly on weekends and converting everything I earn into satoshis,” he added.

He said Bitcoin’s price swings don’t worry him.

“Bitcoin’s volatility doesn’t bother me because I think long-term — when the price drops, I see it as a chance to accumulate more.”

Teased And Misunderstood

Oliveria’s mission wasn’t always celebrated. When he first started, he claimed some of his friends in Limeira laughed and teased him.

“Among some friends, I’m even joked about, especially by those who enjoy gambling and bets,” Oliveira told CCN.

“Still, that doesn’t discourage me — what matters is showing that it’s valuable to invest wisely, even starting small.”

Two years later, the laughter has faded.

Oliveira’s story has now become viral across social media, with thousands of online traders heralding his mission as real “proof of work.”

“I haven’t fully reached my goal yet, but I surprisingly earned the respect of the Bitcoin community, and that already means a lot to me,” he told CCN.

However, despite international recognition, Oliveira claims “only a few people really know me and invest in Bitcoin” in his local city.

Teaching Bitcoin To Younger Generation

Beyond collecting cans, Oliveira has now written four children’s books and developed a memory game aimed at teaching Bitcoin’s principles to families.

“The books and the game are part of a family-friendly Bitcoin education,” he said.

“They teach, in a fun and colorful way, values like freedom, responsibility and cooperation,” he added.

He said his main motivation comes from his two daughters and grandson, who he doesn’t want to make the same mistake he did of investing late.

“I don’t want that to happen to them,” he said.

解读Agent商业、支付与基础设施的真相

作者基于一年来为Agent经济构建基础设施的经验,指出当前Agent商业尚未形成真实、规模化的市场需求,初创公司面临结构性挑战。 文章分析了四个关键场景: 1. **Agent对商户**:目前电商体验中,聊天界面在视觉比价购物上逊于传统界面,商户接入多出于防御性“优化”心态。对话式商业在如外卖等高頻、低决策场景有潜力,但受限于平台开放性和成本。 2. **Agent对API**:开发者现有支付方式(如预付)已能处理低频、小额的API调用成本问题。真正的机会在于服务长尾、小众的供应商市场,但规模有限。 3. **Agent对Agent**:这是长期的愿景,涉及机器间的自动交易与结算,需求真实但当前市场几乎为零,需要专用的基础设施。 4. **Agent对金融**:这是唯一存在现成需求和付费客户的领域。将AI嵌入金融工作流是自然演进,但竞争激烈,老牌机构优势明显。 文章认为,行业巨头因资金充足和战略防御而持续投入,但对初创公司而言,真正的机会并非单纯构建支付层。支付只是更宏大问题——**Agent与人类的协同工作、验证与结算**——的一部分。未来,解决协同问题的公司将主导市场,而非支付服务商。作者团队已转向一个存在真实需求、快速增长且未被充分服务的领域。

Kalshi、MTS 与 a16z 的野望

本文探讨了预测市场在2025年成为投资、加密和媒体领域共同关注焦点的现象,并着重分析了其精神内核的演变及其与风投机构a16z所倡导的“新媒体”愿景的契合。 文章首先回顾了预测市场的思想渊源:从哈耶克关于市场作为分散知识协调机制的观点,到罗宾·汉森设计对数市场评分规则(LMSR)以激励信息真实披露,乃至衍生出的“未来统治”(Futarchy)治理乌托邦构想。 然而,作者指出,a16z在2024-2025年投资估值飙升的预测市场平台Kalshi,为此领域注入了新的精神内涵——“在场感”。在人们与现实世界日益疏离的后现代语境下,预测市场提供了一种通过真金白银下注来介入和“预测”未来的方式,使用户从被动观察者转变为主动的“超级观察者”,从而对抗不确定性与无力感。当足够多人使用并依赖这种媒介时,市场本身将对事件的真实性与重要性获得解释权,这正是a16z构建新媒体帝国的关键拼图。 最后,文章以媒体公司MTS为例,说明a16z的“新媒体”是一种全频段、高烈度的信息工程,旨在“接管时间线”。而Kalshi的核心价值在于,它通过真实的交易数据构建了一种强大的“现实扭曲力场”,其显示的市场概率能深刻影响公众认知与判断,这种赋予私营公司的社会影响力是其获得高估值的根本原因。
