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.
