Criminal Lawyers in Cryptocurrency Fraud

Cryptocurrency fraud is a contemporary manifestation of the classic patrimonial offence of Art. 248 CP, adapted to blockchain architecture and the economy of decentralised digital assets. The protected legal interest remains the victim's patrimony, but the means of commission (distributed technology, smart contracts, centralised and decentralised exchanges, mixers, bridges) introduces technical specificities demanding integrated command of Criminal Law and technological infrastructure. Supreme Court and Provincial Court case-law has consolidated that the nature of crypto-assets does not alter typicity: when sufficient deceit, error in the victim, act of patrimonial disposition (fiat transfer, digital asset transfer) and damage concur, the offence of Art. 248 CP is integrated with the corresponding penalties.

The methods of commission in the crypto ecosystem are extraordinarily diverse and forensic practice identifies recurring patterns. Fake brokers are fraudulent platforms simulating legitimate exchanges, presenting dashboards with fictitious gains to induce new contributions and blocking withdrawals demanding additional payments for "taxes" or "release commissions". DeFi rug pulls consist of coordinated withdrawal of token pool liquidity by developers after raising investment; smart contract audit usually reveals technical "backdoors" allowing unauthorised extraction. Crypto Ponzi schemes simulate staking, yield farming or lending platforms with impossible yields (3-10% daily), paying early investors with new capital until collapse. Fraudulent ICOs raise capital with fictitious whitepapers for non-existent projects. Pump and dump coordinates through Telegram or Discord groups the artificial inflation of low-cap tokens to sell at highs. NFTs with plagiarism or wash trading manipulate prices through self-related operations.

The penalties are calculated under the ordinary Criminal Code: 6 months to 3 years' prison for basic fraud (damage between €400 and €50,000), 1 to 6 years' prison and 6 to 12 months' fine in the aggravated modality of Art. 250 CP (amount over €50,000, mass crime when there are multiple victims, abuse of business credibility), and 4 to 8 years' prison in the hyper-aggravated type when the total accumulated damage exceeds €250,000. To custodial penalties are added proportional fine, civil liability ex delicto with patrimonial damages and, where appropriate, moral damages, and criminal record with effects on immigration and regulated employment. They frequently concur with money laundering under Art. 301 CP when defrauded funds are channelled through mixers, cross-chain swaps or unregulated exchanges, integrating real concurrence with additional penalties.

The technical defense and private prosecution in crypto-fraud require specific tools. For the defence: proof of the speculative nature of the asset (market volatility is not fraud, an 80% loss of a token's value does not imply deceit if the project was real), demonstration of good faith in project operations (existence of auditable code, real technical team, effective intention to fulfil the roadmap), analysis of the applicable regulatory framework (EU Regulation MiCA 2023/1114 on Crypto-Asset Markets, in phased entry from 2024-2025, distinguishes regulated from unregulated assets), and, where appropriate, absence of fraudulent intent when the business fails due to assumed risk. For private prosecution: forensic blockchain tracing with specialised tools (Chainalysis Reactor, Elliptic, TRM Labs) allowing tracing of fund routes through wallets, mixers (Tornado Cash, Wasabi) and bridges to the final cash-out; KYC identification of the holder at regulated exchanges by judicial order; urgent precautionary measures of telematic seizure of identified funds; international judicial cooperation with European authorities and crypto-centric jurisdictions (Singapore, Switzerland, USA).

In current forensic practice, cryptocurrency fraud presents three characteristics making it particularly complex: speed of fund movement (seconds-long transactions on a global scale), pseudonymity of wallets not associated with exchanges, and international jurisdictional dispersion. Organic Law 1/2025 on Justice Service Efficiency, transposition of the MiCA Regulation, the EU Fifth and Sixth Anti-Money-Laundering Directives and consolidated Supreme Court case-law on electronic evidence have raised the standards of action. At Alonso Sala, with 15+ years' experience in economic offences and a multidisciplinary team integrating criminal lawyers and forensic blockchain experts, we undertake both technical defence of crypto entrepreneurs and investors unjustly accused and the private prosecution of crypto-fraud victims, articulating urgent procedural strategies to identify the fraudster, seize funds before the final cash-out and recover assets through national and international judicial channels.
