Prerequisite Concepts: What Is Legal Tender?
Legal tender is a currency recognized by a state’s legal system as an official means of payment and as a valid instrument for settling financial obligations.
From a legal perspective, a creditor cannot refuse payment made in legal tender when the requirements established by applicable regulations are met.
In the eurozone, this term refers to the euro issued by the European Central Bank and the national central banks.
Are foreign currencies legal tender?
Foreign currencies are not legal tender in Spain, although the parties may freely agree that an obligation be settled in U.S. dollars, British pounds, or other currencies.
For accounting and tax purposes, transactions conducted in foreign currency must subsequently be converted to euros, recording the applicable exchange rates and any resulting gains or losses.
What are cryptocurrencies?
Cryptocurrencies are digital assets that use blockchain technology or distributed ledger systems to ensure the integrity and traceability of transactions.
Unlike currencies issued by central banks, cryptocurrencies operate in a decentralized manner and do not rely on a public authority to directly control their issuance or circulation.
Currently, from a European legal perspective, cryptoassets are subject to a specific regulatory framework that has evolved significantly since the sector’s early years.
Can cryptocurrencies serve as a means of payment?
Yes. Cryptocurrencies can be used as a means of payment when the parties voluntarily agree to use them to fulfill an obligation.
This principle stems from the freedom of contract recognized by our legal system. Just as the parties may agree on certain forms of compensation or exchange, they may also agree to use digital assets as consideration.
Therefore, although cryptocurrencies are not legal tender in the strict sense, they can be validly used as a medium of exchange in certain transactions.
In practice, can you pay with cryptocurrency?
The acceptance of cryptocurrencies as a form of payment has increased significantly in recent years.
More and more companies, retailers, and digital platforms are accepting payments in Bitcoin, Ethereum, or other cryptoassets, especially in the technology, e-commerce, and digital services sectors.
In addition, the emergence of specialized providers has facilitated automatic conversion between cryptocurrencies and fiat currency, reducing some of the barriers that existed during the market’s early years.
Can you get cash using cryptocurrency?
There are currently many ways to convert crypto assets into fiat currency.
In addition to regulated exchanges, certain financial platforms and authorized providers facilitate the conversion of cryptocurrencies to euros via bank transfers or compatible payment systems.
These transactions may give rise to tax and reporting obligations that must be analyzed on a case-by-case basis.
What is behind the boom in cryptocurrencies?
The growth of cryptocurrencies is driven by a number of factors.
On the one hand, many investors view certain digital assets as an investment alternative or a store of value. On the other hand, blockchain technology has demonstrated its ability to facilitate international transactions, tokenize assets, and develop new decentralized economic models.
The emergence of Web3 applications, decentralized finance, and tokenization systems has significantly expanded the scope of this technology beyond Bitcoin.

Current Regulation of Cryptoassets and the MiCA Regulation
One of the most significant changes in the sector has been the adoption of the MiCA Regulation, which establishes the first specific European regulatory framework for crypto-assets and related service providers.
MiCA introduces regulatory requirements for crypto-asset issuers, exchange platforms, custodians, service providers, and certain tokenization models.
It also complements other regulatory obligations related to compliance and anti-money laundering, investor protection, and financial supervision.
Adapting to this new regulatory framework is essential for any company operating within the European blockchain ecosystem.
