Bitcoin, Ethereum, and hundreds of other digital currencies have gone from a niche pursuit to a mainstream fascination in Spain. The ease of trading through apps, the promise of innovation, and the constant buzz on social media have convinced thousands of people to invest. Yet that enthusiasm has opened the door to a parallel world of crime.
With little regulation, high levels of anonymity and widespread confusion over how cryptocurrencies really work, fraudsters have found fertile ground.
The National Cybersecurity Institute (INCIBE) warns that criminals are exploiting the boom with scams designed to part investors from their savings. Unlike traditional financial fraud, these schemes thrive in the decentralised nature of crypto, where recovering stolen funds is virtually impossible.
How the scams work
The methods vary, but the aim is always the same: to steal access to digital wallets or convince investors to hand over their money. Some fraudsters mimic well-known trading platforms, sending emails that trick victims into entering their passwords on fake websites. Others build elaborate schemes promising spectacular profits in record time, playing on greed and fear of missing out.
There are also malicious apps that pose as wallets or investment tools but exist only to drain funds, and market manipulations where the value of obscure tokens is artificially inflated to lure in unsuspecting buyers before collapsing. Once a private key or recovery phrase is compromised, the attackers gain full control of a wallet and can empty it in seconds.
Warning signs you shouldn’t ignore
Scams often follow a familiar pattern. Offers of guaranteed profits or miraculous returns should immediately raise suspicion. So too should pressure to act quickly, with claims of “limited opportunities” or “exclusive deals” that demand instant decisions. Many fraudsters rely on unofficial contact, whether through social media messages, WhatsApp or emails with dubious senders.
Transparency is another crucial test. Legitimate companies are usually clear about who they are, where they operate and which regulations they follow. Fraudsters, by contrast, hide behind vague names and anonymous websites, making it difficult to trace them once money disappears.

Protecting your investment
Defence begins with caution. Investors are advised to stick with reputable exchanges and wallets that are widely trusted and reviewed, and to activate two-factor authentication to add an extra layer of security. Private keys and recovery phrases must remain private at all times. Before committing money, take time to research the platform and check independent sources such as the Spanish securities regulator (CNMV).
It also pays to slow down. Scammers rely on urgency to push people into rash decisions. A pause to verify a website address, to confirm an app is genuine, or simply to think twice can prevent devastating losses.
If you’ve been caught out
Anyone who suspects they have fallen victim should stop contact with the fraudsters immediately and avoid sending further funds. Gathering evidence — from messages and emails to wallet addresses and transaction details — is vital. With that information, victims should report the case to the police or Guardia Civil’s cybercrime units. INCIBE also offers confidential advice through its Cybersecurity Helpline, available by dialling 017, via WhatsApp at 900 116 117, or on Telegram (@INCIBE017).
Prevention over regret
Cryptocurrencies remain a space of genuine opportunity, but also one where knowledge is the strongest defence. In a market brimming with dazzling promises, scepticism is healthy. Protecting your assets means refusing to rush, demanding transparency and never sharing the keys to your wallet. For investors in Spain, understanding the risks of crypto scams is no longer optional — it is essential.
