Bank liability in crypto fraud: when can banks be held responsible?
More and more investors are putting money into cryptocurrencies — often via supposedly reputable trading platforms. Payments are frequently processed via bank transfers. In these cases the question arises: can banks be liable when they execute transfers to fraudulent crypto platforms or foreign accounts?
The legal situation is complex, but investors should be aware of the following scenarios in which a liability for damages can arise:
Breach of duties to review and to warn
Banks are generally obliged to scrutinise conspicuous transactions. If a transfer abroad goes to a fraudulent account — especially with very high amounts, unusual payees or multiple warning signals — liability can arise if the bank does nothing despite recognisable warning signs.
Example: a transfer to a British company with the reference “Bitcoin Invest”, without any documented customer context or understanding, could trigger a duty to warn. Particularly in phishing cases, we have obtained damages in court for many of our clients.
Bank staff actively give wrong advice or fail to warn
If bank employees knew or should have known of the fraudulent nature of a recipient (e.g. through internal warning systems or ongoing investigations). Foreign banks, trading platforms or cybercrime insurers may also be obliged to pay. We are happy to examine this for you.
Duty to recall upon detected fraud
If fraud is reported by the customer — especially shortly after the transfer — the bank must immediately attempt to recall the payment. If this recall is omitted or made too late, this can likewise give rise to a liability for damages.
Reporting crypto fraud — how to proceed
If you have become a victim of crypto trading fraud, you should act quickly:
- 1Stop payments immediately and make no further transfers.
- 2Preserve evidence: wallet addresses, transfer receipts, chat messages, emails.
- 3Engage a lawyer for crypto fraud to enforce claims for damages and to initiate criminal proceedings through the firm.

Interview: specialist lawyer Dr. Stephan Greger on the topic
What role does crypto fraud play in the crypto market?
Crypto fraud has increased sharply in recent years. While the market offers opportunities, fraudsters exploit the trust of investors. The losses for investors are often considerable.
What legal options do those affected have?
Affected investors can turn to specialised firms. We review claims, file criminal complaints and pursue damages against fraudsters, banks or platforms.
What particular challenges are there?
The anonymous nature of cryptocurrencies and international structures make investigation difficult. International cooperation with law-enforcement authorities is often required.
What preventive measures can investors take?
Only trade on reputable exchanges, heed warning signals and do not believe unrealistic profit promises. Be cautious with unknown start-ups and ICOs.
Prevention — how to recognise and avoid crypto fraud
- Be sceptical of unrealistically high return and profit promises.
- Never share private keys or recovery (seed) phrases.
- Only trade on reputable, regulated crypto exchanges and check for licences.
- Do not make deposits with unknown start-ups or ICOs.
- Always use HTTPS addresses and keep security software up to date.
- Enable two-factor authentication (2FA).
- Always question unknown contacts and be wary of pressure to invest quickly.
- If in doubt: secure your wallets, contact a specialised law firm, file a report.
