Earning money with Ethereum, the popular cryptocurrency, is a reality for many people in Spain right now. They aren't digital ninjas or anonymous hackers. They are regular individuals with a curious mindset and some technical initiative.
In February, Mario Chamorro, a consultant based in Madrid, was discussing various cryptocurrencies with a friend when Ethereum came up. He initially didn’t pay much attention. However, by May, as its value began to rise significantly, he decided to look deeper into it. With growing interest—and after reading a couple of books on the topic—Chamorro and his brother set up their own mining rig to mine Ether, Ethereum's native currency.
What Is Ethereum Mining?
Mining Ethereum involves contributing your computer’s processing power to a global decentralized network. In return, you earn a share of Ether proportional to the computational effort you provide. The system charges a small fee, known as "gas," for each transaction to keep the network operational.
However, mining solo with a single computer isn’t practical. As Chamorro explains, "No matter how many graphics cards you have, you can’t compete against the millions of devices worldwide." That’s why most miners join a "mining pool." By pooling resources with thousands of others, each participant earns a proportional share of the rewards.
Why Mine Ethereum Instead of Bitcoin?
Many new miners are turning to Ethereum instead of Bitcoin for one simple reason: accessibility. Mining Bitcoin is rarely profitable for the average person due to intense competition from large-scale professional mining operations. Ethereum’s entry barrier is lower.
Chamorro notes, "With Ethereum, it becomes profitable once the currency reaches around $200. The higher the price of Ether, the more you earn." On a single day in July, for example, Ether’s price fluctuated between $206 and $256, making it a profitable opportunity for small-scale miners.
Setting Up a Mining Operation
Getting started requires hardware—especially high-end graphics cards (GPUs). There’s currently a global shortage of these components because of high demand from cryptocurrency miners. Brands like NVIDIA have even announced plans to produce mining-specific GPUs.
Chamorro began by experimenting with his personal computer but soon realized it lacked sufficient power. After calculating potential risks and returns, he and his brother invested in 12 high-end graphics cards. Some specialized components, like mining-specific cables, had to be shipped from Hong Kong, causing weeks of delay.
Once all the parts arrived, they assembled two mining rigs using online guides. These have been running continuously for about a month, generating approximately three Ether monthly. After deducting electricity costs (around €180), the operation remains profitable. They expect to recoup their initial hardware investment in under a year.
Is Ethereum Mining Sustainable?
The rising number of daily Ethereum transactions suggests growing adoption. While this could mean further price increases—similar to Bitcoin’s historic rise—it also raises concerns about a potential market bubble.
Chamorro acknowledges the risk: "If Ether’s value dropped to zero tomorrow, we could still resell the hardware at about 60% of its original cost. That felt safer than investing directly in the currency."
Alternative Ways to Get Involved
Not everyone wants to build a mining rig. Raúl Marcos, a programmer, initially mined Ether but now prefers buying and selling it directly. He acquired some of his Ether for less than $7 per unit—and recalls when it was available for just $1.
Another accessible option is cloud mining, where users rent computational power from third-party services. This allows participation without deep technical knowledge or hardware investments.

Understanding the Miner Mindset
Miners often have mixed motivations. While profitability is a major driver, many are also drawn to Ethereum’s decentralized nature. The idea of a currency free from government control or bank intermediation appeals to libertarian and tech-oriented individuals.
Chamorro sums it up: "We did this to better understand how cryptocurrencies work. There’s no better way to learn than by doing it yourself. Of course, making money is important, but the philosophical aspect matters too—Ethereum depends solely on supply and demand."
Frequently Asked Questions
What is the minimum investment to start mining Ethereum?
A basic setup with a single GPU can cost a few hundred dollars. However, to see meaningful returns, a multi-GPU rig is recommended, which may require an initial investment of $1,500 or more.
How much electricity does Ethereum mining consume?
Mining rigs run 24/7 and can significantly increase your electricity bill. A medium-scale setup may cost between $100–200 monthly, depending on local energy rates.
Is it better to mine solo or join a pool?
For most individuals, joining a mining pool is essential. Solo mining is unlikely to yield returns due to the high level of competition and computational power required.
Can I mine Ethereum with a regular laptop?
While technically possible, it is not efficient or profitable. Laptops lack the processing power and cooling capacity needed for serious mining.
What happens if the price of Ethereum crashes?
While a price drop would reduce profitability, miners can repurpose or resell their hardware to recover part of the initial cost.
Are there alternatives to buying expensive hardware?
Yes, cloud mining services allow you to rent hashing power. This lowers the entry barrier but may offer smaller returns over time.
Ethereum mining offers an intriguing blend of technological engagement and financial opportunity. Whether you choose to build a rig, join a pool, or explore cloud mining, understanding the basics is the first step toward informed participation.
