‘They Laughed At Me’: How A Brazilian Man Selling Cans For Bitcoin Is Turning Doubters Into Believers

. 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.

Uncovering the Truth About Agent Commerce, Payments, and Infrastructure

Decoding Agent Commerce, Payments, and Infrastructure: The Reality Over the past year, I've been building infrastructure for the Agent economy, engaging with major players like Stripe, Visa, Coinbase, Google, and dozens of startups. A clear conclusion emerges: true, large-scale demand does not yet exist. Startups face structural challenges. Data points illustrate this gap. Stripe's Agent commerce platform has over 1,000 merchants but only single-digit transacting agents. Visa's Agent payment token requires 9-month KYC and a $250M revenue threshold, accessible only to giants like Amazon. On-chain analysis reveals actual daily Agent transaction volume is around $17k, half of which are test transactions. The article analyzes four potential markets: **1. Agent-to-Merchant (A2M):** Current AI shopping UX is often inferior to traditional e-commerce for visual, comparison-heavy purchases (clothing, electronics). Chat interfaces are a step back. Real merchant interest is defensive "Agent Engine Optimization," fearing future obsolescence, not current demand. Potential exists in high-frequency, low-decision purchases (e.g., food delivery) or simplifying terrible UX (complex checkouts, non-native shoppers), but these require massive consumer distribution channels dominated by giants like DoorDash and Amazon. **2. Agent-to-API (A2A):** Developers already have subscriptions and billing for core APIs (compute, data). The argument for micro-payments via crypto for sub-dollar API calls is addressed by pre-paid balances today. The deeper issue is supplier resistance; major SaaS firms rely on enterprise contracts, not fractional cent pricing. Opportunity lies in the long tail of niche services, but this is a smaller market catering to developers, a historically low-paying group. **3. Agent-to-Agent (A2A):** This remains a theoretical long-term vision with near-zero current transaction volume. It involves unique challenges: discovery, trust, negotiation, dispute resolution. When it materializes, it will require a fundamentally new settlement infrastructure for high-speed, variable-value, multi-party transactions. It's a real long-term bet, but not the current market. **4. Agent-to-Finance (A2F):** This is the only category with existing, paying demand. Integrating AI into financial workflows (trading, portfolio management) is a natural evolution and enables new capabilities like autonomous rebalancing. However, competition favors incumbents with regulatory licenses, compliance infrastructure, and existing client relationships. **The Real Issue:** Why is infrastructure still being built? Incumbents can afford long-term bets, and payment companies see every problem as a nail for their payment hammer. However, payment is just one piece. The core challenge is *coordination*—orchestrating work between Agents and humans, verifying outcomes, and settling results. Payment is part of settlement, which is part of coordination. Companies that solve the coordination problem will subsume payments, not the other way around. Startups lack the infinite runway of giants and must find today's real market, which, after a year of exploration, lies outside these four categories—in an area with real, growing, and underserved activity.

Kalshi, MTS, and a16z's Ambition

The article "Kalshi, MTS, and a16z's Ambition" explores prediction markets as a focal point of excitement in 2025 for investors, crypto enthusiasts, and media. It traces their intellectual lineage from Friedrich Hayek's ideas on dispersed knowledge and market coordination to Robin Hanson's Logarithmic Market Scoring Rule (LMSR), which incentivizes truthful information sharing. The piece argues that a16z's significant investment in prediction market platform Kalshi (valued at $220B) transcends mere financial speculation. a16z frames prediction markets as a new form of "media" that provides "presence"—a way for individuals to actively engage with and influence world events through financial stakes, countering postmodern detachment. By wagering on outcomes, users become "super observers," and the market's aggregated probabilities gain authoritative power to define event truth and importance. The article uses media company MTS ("Monitoring The Situation") as a case study of a16z's "new media" strategy: rapidly producing high-intensity, multi-format content to "take over the timeline." However, prediction markets like Kalshi are presented as the ultimate piece in this media empire. Their real-money, crowd-sourced probabilities possess a unique "reality distortion field" and perceived objectivity, potentially swaying public opinion and granting a private company unprecedented interpretive power over reality. Ultimately, Kalshi's immense valuation is attributed not just to its exchange model, but to its role as a foundational component in a16z's envisioned new media landscape, where prediction markets define narrative and truth.

US Stocks Suffer Worst Plunge Since 2025: Three Triggers Ignite Tech Stock Valuation Reset

The US stock market experienced its most severe sell-off since the 2025 tariff crisis on June 5th, 2025. The Nasdaq Composite plummeted 4.18%, the S&P 500 fell 2.64%, and the Dow Jones dropped 695 points. The panic stemmed from three converging factors. First, Broadcom's earnings report ignited fears of a slowdown in AI growth. While its AI chip revenue surged 143% YoY to $10.8B, its Q3 AI revenue guidance of $16B fell short of the $17.2B consensus. This triggered a massive sector-wide sell-off, with the Philadelphia Semiconductor Index crashing 10.26% and semiconductor stocks losing roughly $1.3 trillion in market value in a single day. Second, a shockingly strong May jobs report crushed hopes for Federal Reserve rate cuts. Non-farm payrolls added 172,000 jobs, doubling expectations. This robust data, combined with persistently high oil prices above $92/barrel due to the ongoing Iran war and blockade of the Strait of Hormuz, drastically increased market expectations for a potential Fed rate hike instead of a cut. Higher interest rates compress the valuations of growth-heavy tech stocks. Third, the prolonged Iran conflict continues to fuel inflationary pressures, complicating the Fed's policy decisions and undermining the "inflation is tamed" narrative. Together, these events challenged the twin pillars of the market rally: the "limitless AI growth" story and expectations for imminent monetary easing. The sell-off spread globally, impacting Asian and European markets and cryptocurrencies. The article posits this is likely a severe "valuation repricing" rather than the end of the AI story. The underlying demand for AI remains strong, but investor expectations for growth speed and the prices they are willing to pay are being recalibrated. Key upcoming factors include the June FOMC meeting, future AI company earnings, and developments in the Iran conflict.

From Madison Square Garden to Kalshi: Prediction Markets Break into the NBA Finals

From Madison Square Garden to Kalshi: Prediction Markets Break into the NBA Finals Prediction markets are playing a significant role in the 2026 NBA Finals, particularly around the New York Knicks' unexpected 2-0 series lead. Platforms like Kalshi and Polymarket have seen massive trading volumes, exceeding hundreds of millions of dollars on championship and related markets. Their influence extends beyond online trading. Kalshi's official partnership with Madison Square Garden has given it prominent physical branding at the arena. Furthermore, local businesses like The Jeffrey bar are using prediction market contracts to hedge the risk of game-result-based promotions, turning potential losses into manageable costs—a concept similar to the famous "Mattress Mack" strategy from traditional sports betting. These markets differentiate themselves by offering a wider, more entertainment-focused range of "event contracts" beyond typical game outcomes, such as predicting celebrity attendance. They also have broader accessibility across the U.S. compared to age- and location-restricted traditional sportsbooks. However, their rapid integration into sports raises regulatory and ethical questions. The NBA is cautiously engaging, discussing integrity frameworks with regulators like the CFTC. While the league permits minor investments like Giannis Antetokounmpo's stake in Kalshi, it advocates for strict rules to prevent insider trading. Many fans express concern on platforms like Reddit, fearing that the close ties between prediction markets, the league, and players could compromise the game's integrity. The NBA Finals has thus become a high-stakes testing ground, showcasing prediction markets' commercial potential while challenging traditional boundaries between financial trading, entertainment, and gambling.
