Cryptocurrencies have gone from being a simple technological curiosity to becoming a practical tool in real-world transactions, including the real estate market. In Spain, this phenomenon began to take shape with the first sale of a property paid entirely in Bitcoin in March 2021, and has continued to evolve with more ambitious transactions, such as the recent purchase of a home in Madrid for €1.5 million in February 2025. These milestones show how Bitcoin is transforming the real estate sector, opening up new possibilities for buyers and sellers.
The first sale with Bitcoin in Spain
The first step towards this real estate revolution occurred in Seville, in the Polígono San Pablo, where a flat was sold for 2.5 Bitcoin (BTC), equivalent to around 117,500 euros at the time, with Bitcoin trading at around 47,000 euros per unit. This transaction, carried out in March 2021, was historic not only for being the first of its kind in Spain, but also for the 28% profit obtained by the seller, thanks to the revaluation of the cryptocurrency since its initial acquisition. The operation was facilitated by a real estate agency that accepted Bitcoin as payment, although the public deed and taxes were registered in euros, adapting to current regulations.
The process was simple but innovative: the buyer transferred the 2.5 BTC from his digital wallet to the seller's, an operation verified in minutes by the blockchain. The notary certified the transfer, converting the value to euros according to the current exchange rate to comply with tax requirements. This speed and low commissions stood out as advantages over traditional bank transfers, setting a precedent for future operations.
A leap forward: Madrid, 1.5 million euros in Bitcoin
Almost four years later, in February 2025, the Spanish real estate market took another big step with the purchase of a property in Madrid for 1.5 million euros, paid in Bitcoin by a Hong Kong businessman. As reported by CriptoFácilThis transaction was made possible thanks to the collaboration between Bit2Me, Complianzen and InmoCrypto, companies that joined forces to ensure a safe and regulated process. The operation, which lasted approximately 20 days, included real estate management, regulatory compliance, banking coordination and notarial procedures, with the final conversion of Bitcoin to euros for the seller.
This sale not only reflects the growing acceptance of cryptocurrencies, but also their potential to facilitate international transactions. The property, valued at €1.5 million, demonstrates how Bitcoin can be a viable alternative for global investors, avoiding the delays and restrictions of traditional financial systems. Bit2Me highlighted that this operation is “the beginning of a blockchain-based real estate sector”, a model that could be expanded to other countries.
Advantages and challenges of using Bitcoin in real estate
Both cases illustrate the advantages of using Bitcoin: speed, reduction of intermediaries and costs, and greater privacy in transactions. For investors with crypto assets, this modality allows diversification without converting their funds to fiat, something especially useful in volatile markets. However, Bitcoin's volatility remains a challenge; for example, the seller from Seville benefited from an upward trend, but a sudden change could have altered the outcome.
Regulation also raises questions. Although Spain allows the use of cryptocurrencies as a means of payment, the lack of a specific framework creates uncertainty on tax and money laundering issues. In both operations, taxes were paid in euros, suggesting that the full integration of cryptoassets in the sector still requires legal adjustments.

The future of crypto real estate transactions
From selling in Seville to trading in Madrid, the use of Bitcoin in real estate has evolved, attracting international investors and innovative companies. Platforms such as InmoCrypto and Bit2Me are leading this change, while other countries, such as Portugal and Mexico, report similar trends. As blockchain technology matures and cryptocurrencies gain legitimacy, the real estate market could become more accessible and efficient.
These cases are just the beginning. For crypto transactions to become mainstream, it will be crucial to overcome volatility, clarify regulations and educate market players. For now, Bitcoin purchases in Spain, from €117,500 in Seville to €1.5 million in Madrid, symbolise a future where digital finance and real estate converge in a transformative way.
