Civil Law and Crypto Exchange Consumer Compensation Claims in Europe

1. Introduction

Crypto-exchange consumer compensation claims arise when an individual customer suffers loss because a cryptocurrency exchange or crypto-asset service provider allegedly:

blocks an account;

refuses or delays withdrawals;

loses or misappropriates crypto-assets;

executes an order incorrectly;

suffers a cyberattack;

provides misleading information;

charges undisclosed fees;

breaches custody obligations;

applies an unfair contractual term;

terminates the customer's account;

fails to return crypto-assets; or

becomes insolvent.

The European legal position has changed substantially with the Markets in Crypto-Assets Regulation (MiCA), Regulation (EU) 2023/1114. MiCA now contains specific obligations concerning custody, segregation, complaints and liability. For custody services, Article 75 requires a contractual framework, segregation of client assets and liability for loss attributable to the crypto-asset service provider, capped at the market value of the lost crypto-asset when the loss occurred. (ESMA)

However, MiCA does not replace ordinary civil and consumer law. Contract law, unfair-terms law, private international law and national tort/delict rules can remain important.

A particularly important point is that direct European case law specifically about crypto-exchange consumer compensation is still developing. The cases below therefore include both direct crypto-exchange authorities and broader CJEU consumer/financial cases that provide the legal principles courts are likely to apply.

2. Meaning of a Crypto-Exchange Consumer Claim

A typical relationship is:

Consumer

↓

Crypto-exchange / Crypto-Asset Service Provider (CASP)

↓

Trading / custody / transfer / exchange service

The consumer may claim:

"I entrusted my crypto-assets or money to the exchange, and the exchange failed to provide the service promised."

The legal claim can be:

Contractual

Failure to perform the exchange agreement.

Tort/delict

Negligent conduct caused financial loss.

Consumer-law claim

An unfair term or misleading practice harmed the consumer.

Regulatory claim

The exchange violated MiCA or another applicable regulatory obligation.

Restitution claim

The customer seeks return of crypto-assets or money.

3. Important Current EU Framework — MiCA

MiCA is central to modern European crypto-exchange disputes.

For a crypto-asset service provider providing custody and administration, Article 75 requires an agreement specifying matters such as:

the service;

custody policy;

authentication;

security systems;

fees;

applicable law. (ESMA)

The provider must also:

maintain records of client positions;

protect client assets;

minimise risks from fraud, cyber threats and negligence;

return assets or means of access as soon as possible;

segregate client assets from its own assets. (ESMA)

Most importantly for compensation claims, Article 75(8) provides liability for loss of crypto-assets or means of access where the incident is attributable to the CASP. The liability is capped at the market value of the crypto-asset at the time of loss. (ESMA)

4. Complaints Before Litigation

MiCA Article 71 requires CASPs to maintain effective and transparent complaints procedures.

Consumers must be able to:

submit complaints free of charge;

receive information about the complaints procedure;

have complaints investigated;

receive the outcome within a reasonable period. (ESMA)

Competent national authorities must also establish procedures through which clients and consumer associations can complain about alleged MiCA infringements. (ESMA)

Therefore, a consumer may have several routes:

Internal complaint → regulator → ADR/consumer mechanism → civil court

5. Case Law 1 — Ang v Reliantco Investments Ltd [2019] EWHC 879 (Comm)

Importance: Cryptocurrency investor can be a consumer

This is one of the most important European authorities for determining whether a cryptocurrency investor qualifies as a consumer.

Ms Ang, an individual of substantial means, traded Bitcoin futures through the UFX platform operated by Reliantco.

The question was whether she was a consumer for the purposes of the Brussels jurisdiction rules.

The court held that speculative investment in Bitcoin was not necessarily a business activity merely because it involved substantial money or sophisticated financial transactions. Later European litigation has continued to cite Ang on the consumer/non-consumer distinction. (Bailii)

Principle

A person does not automatically cease to be a consumer simply because:

they have substantial wealth;

they make speculative investments;

they understand financial products;

they trade cryptocurrency.

Importance for compensation

This can determine whether the customer receives the special jurisdictional protection available to consumers.

6. Case Law 2 — Payward v Chechetkin [2023] EWHC 1780 (Comm)

Importance: Kraken cryptocurrency dispute

Payward, the operator associated with Kraken, brought proceedings concerning a customer who had traded cryptocurrency.

The court considered whether the customer was a consumer and discussed the significance of Ang v Reliantco.

The judgment confirms the importance of examining the purpose for which the individual entered the transaction rather than simply assuming that cryptocurrency trading is commercial activity. (Bailii)

Principle

A cryptocurrency customer may still qualify as a consumer where the activity is undertaken primarily for personal purposes.

Compensation relevance

Consumer status can affect:

jurisdiction;

applicable consumer protections;

unfair-term analysis;

enforceability of contractual clauses.

7. Case Law 3 — Soleymani v Nifty Gateway LLC [2022] EWCA Civ 1297

Importance: Crypto platform + consumer arbitration

This case involved an NFT purchased through the Nifty Gateway platform.

The customer was a UK resident and the platform's terms contained:

New York governing law;

New York arbitration;

an arbitration clause.

The claimant argued that the terms were unfair under consumer law.

The Court of Appeal considered whether the arbitration arrangement could prevent the English courts from examining the consumer's objections. (Bailii)

Principle

An online crypto/digital-asset platform cannot necessarily rely on an international arbitration clause simply because the customer clicked "accept".

Consumer-protection rules may affect the enforceability of:

arbitration clauses;

foreign jurisdiction clauses;

governing-law clauses.

Application to exchanges

Suppose:

A French consumer uses a US-based crypto exchange.

The exchange's terms say:

"All disputes must be arbitrated in New York."

The consumer may still have arguments based on mandatory consumer protection and jurisdiction rules.

8. Case Law 4 — Skatteverket v Hedqvist, C-264/14

Importance: Legal classification of Bitcoin exchange services

In Hedqvist, the CJEU examined transactions exchanging traditional currency for Bitcoin and vice versa.

The Court held that such Bitcoin exchange transactions constituted a supply of services for consideration and fell within the VAT exemption for transactions concerning currencies used as means of payment. (Legal Guide)

Importance

Although Hedqvist was a VAT case rather than a compensation case, it is fundamental to understanding the legal characterisation of cryptocurrency exchange activity in EU law.

Principle

A crypto exchange providing exchange services is providing an economically identifiable service.

This supports analysing the relationship through:

contract law;

service-provider duties;

consumer law;

regulatory obligations.

9. Case Law 5 — FIBO Markets v J.P., C-346/25

Importance: Recent EU consumer financial-contract authority

The CJEU decided FIBO Markets Ltd v J.P., C-346/25, on 18 June 2026.

The case concerned CFDs rather than spot cryptocurrency exchange.

The Court examined Rome I, consumer contracts and financial instruments. It distinguished the financial terms governing execution of a consumer's order from framework-contract terms allowing the professional to refuse or execute an order differently. (Curia)

Why it matters for crypto exchanges

Crypto platforms frequently use framework agreements containing clauses concerning:

execution;

suspension;

cancellation;

price determination;

order rejection;

account restrictions.

FIBO Markets illustrates that European courts may distinguish between:

the financial characteristics of a transaction

and

the broader contractual relationship between consumer and platform.

This distinction can become important when determining the applicable law.

10. Case Law 6 — N26 / Bitpanda Crypto Litigation, Tribunal judiciaire de Pontoise, RG No. 25/00726, 9 January 2026

Importance: Direct European crypto-service dispute

This is a particularly useful recent French civil-law authority.

The customer used N26 Crypto, through which crypto trading was technically provided by Bitpanda.

The customer placed Bitcoin sale orders which were not executed for a period.

He sought, among other things:

release/transfer of his Bitcoins;

compensation for material loss;

compensation for moral loss.

The court found that the actual execution of crypto orders fell within Bitpanda's role, while N26 had not itself performed the Bitcoin blocking complained of. However, the court found that N26 had itself committed a civil fault by giving the customer misleading/inadequate explanations about the source of the blocking. The court provisionally assessed the resulting moral damage at €3,000, while rejecting the claimed material damages at that interim stage because the underlying reasons for the trading block remained seriously disputed. (Cour de Cassation)

Principle

This case illustrates an important concept:

Liability may be divided between the platform through which the customer accesses crypto services and the underlying crypto service provider actually executing or holding the assets.

Practical importance

A customer should identify:

who contracted with the customer;

who executed the transaction;

who held the crypto-assets;

who controlled the wallet;

who blocked the transaction;

who communicated with the customer.

11. Case Law 7 — OLG Frankfurt, 19 September 2025, 7 U 80/24

Importance: Bitcoin loss and insurance claim

The German Higher Regional Court of Frankfurt considered a dispute concerning legal-protection insurance and a claim involving the equivalent of 15.894 Bitcoin.

The court recognised an underlying damages claim relating to that amount of Bitcoin for purposes of the insurance dispute. (Hessenrecht)

Principle

Crypto-related financial claims can be sufficiently identifiable for ordinary civil litigation.

The dispute does not become legally meaningless merely because the underlying asset is Bitcoin.

Compensation relevance

A court can potentially deal with:

quantity of Bitcoin;

euro valuation;

contractual entitlement;

damages;

insurance coverage.

The precise valuation date remains crucial.

12. Case Law 8 — Eternity Sky Investments Ltd v Zhang [2024] EWCA Civ 630

Importance: Consumer status in investment transactions

The Court of Appeal discussed the consumer/business distinction and referred to Ang v Reliantco.

It emphasised that the objective nature of the transaction is important when deciding whether an individual is acting as a consumer. (Bailii)

Crypto relevance

The case is useful because crypto-exchange defendants may argue:

"The customer was an investor, therefore not a consumer."

That conclusion cannot simply be assumed.

The court must examine the circumstances and purpose of the transaction.

13. Case Law 9 — Kásler v OTP Jelzálogbank, C-26/13

Importance: Transparency and unfair contractual terms

Although Kásler did not concern cryptocurrency, it is a major CJEU consumer-contract authority.

The CJEU examined transparency and unfairness in consumer contractual terms.

Application to crypto exchanges

Exchange terms may contain clauses dealing with:

spread;

conversion rates;

liquidation;

account suspension;

withdrawal fees;

liability exclusions;

unilateral changes.

A consumer should be able to understand the economic consequences of important terms.

14. Case Law 10 — Pannon GSM, C-243/08

Importance: Court's role in unfair terms

In Pannon GSM, the CJEU strengthened the role of national courts in examining unfair consumer terms.

This is important for crypto exchanges because their terms are usually:

pre-drafted;

online;

non-negotiated;

lengthy;

technically complex.

The EU Unfair Terms Directive applies to standard consumer contracts and treats a non-negotiated term as potentially unfair where it causes a significant imbalance contrary to good faith. (EUR-Lex)

15. Legal Classification of the Crypto-Exchange Contract

A crypto-exchange relationship can contain several contracts simultaneously.

Contract 1 — Account agreement

Creates the customer's exchange account.

Contract 2 — Trading agreement

Allows purchase and sale of crypto-assets.

Contract 3 — Custody agreement

Applies where the exchange holds crypto-assets on behalf of the customer.

Contract 4 — Transfer service

Concerns movement of crypto-assets to another wallet.

Contract 5 — Fiat/payment service

Concerns deposits and withdrawals in euros or another currency.

The applicable legal regime can differ between these services.

16. Crypto Custody and Compensation

MiCA Article 75 is particularly important.

Where a CASP provides custody:

It must

maintain client records;

safeguard assets;

segregate client assets;

establish security procedures;

facilitate return;

provide position statements;

protect against insolvency risks. (ESMA)

Liability

Where loss is attributable to the CASP, it is liable to the client.

The statutory cap is generally:

market value of the crypto-asset at the time the loss occurred. (ESMA)

17. Example — Exchange Hack

Suppose:

A consumer has 2 BTC on a regulated European exchange.

A hacker obtains access because the exchange failed to maintain adequate security.

The exchange says:

"All cryptocurrency transactions are irreversible, so we have no responsibility."

That defence would not automatically dispose of the claim.

The court would consider:

Was the exchange providing custody?

Was the loss attributable to the exchange?

Were security obligations complied with?

Was the customer's own conduct relevant?

Was the loss caused by an external blockchain problem?

What was the market value when the loss occurred?

MiCA Article 75 specifically addresses provider liability for attributable loss. (ESMA)

18. Example — Unauthorized Transfer

Suppose an attacker transfers:

5 ETH

from the customer's exchange account.

Possible questions include:

Was the transfer authorised?

Was the customer's authentication compromised?

Did the exchange follow its security procedures?

Did the exchange detect abnormal behaviour?

Was there negligence?

Did the customer share authentication credentials?

Does MiCA apply to the particular service?

Does another payment-services regime apply to the fiat component?

The liability analysis therefore depends heavily upon the precise service being provided.

19. Exchange Freezes Customer Account

This is another major source of litigation.

An exchange may freeze an account because of:

AML requirements;

sanctions;

suspicious transactions;

fraud investigation;

technical problems;

court orders;

regulatory instructions.

The customer may nevertheless claim:

breach of contract;

wrongful withholding;

negligent communication;

unfair contractual treatment;

damages caused by the delay.

The French N26/Bitpanda decision illustrates how the distinction between the actual blocker and the intermediary communicating the decision can become critical. (Cour de Cassation)

20. Lost Profits and Crypto Price Appreciation

This is one of the hardest damages questions.

Suppose:

customer owns 10 BTC;

exchange freezes account;

Bitcoin rises substantially;

customer claims the entire increase as damages.

The court must determine:

Was the price increase legally recoverable?

Relevant questions include:

Was the customer actually prevented from selling?

Was the sale order valid?

Was the exchange contract breached?

Was the price increase foreseeable?

Did the customer have alternative means of trading?

Was the customer under a duty to mitigate loss?

What valuation date applies?

The French Pontoise decision is instructive because the court did not simply accept a hypothetical profit calculation where the underlying responsibility for the trading restriction remained disputed. (Cour de Cassation)

21. Market-Price Volatility

Crypto-assets create an unusual damages problem.

Suppose:

1 BTC = €80,000 when the exchange loses the customer's BTC.

Later:

1 BTC = €100,000.

Later:

1 BTC = €50,000.

Which value should determine damages?

Potential approaches depend on the applicable law and claim:

value at date of loss;

value when breach became known;

value at judgment;

specific performance/restoration of the crypto;

contractual valuation mechanism.

MiCA provides a particularly important statutory reference for custody liability by using the market value at the time the loss occurred as the liability cap under Article 75(8). (ESMA)

22. Compensation in Crypto or Fiat?

A customer may request:

A. Return of the cryptocurrency

Example:

"Return my 2 BTC."

B. Euro compensation

Example:

"Pay me the euro value of the 2 BTC."

C. Both

Generally, a claimant cannot recover twice for the same loss.

The appropriate remedy depends upon:

contract;

national civil law;

nature of the asset;

availability of restitution;

valuation date;

applicable MiCA provisions.

23. Unfair Liability Disclaimers

Crypto platforms commonly use terms attempting to limit responsibility for:

hacking;

network failures;

market volatility;

lost keys;

service interruption;

third-party failures.

Under EU consumer law, a standard term may be unfair if it causes a significant imbalance contrary to good faith. (EUR-Lex)

Example

"The exchange is never liable for any loss of customer crypto-assets, regardless of cause."

Such a clause should not automatically be treated as enforceable.

The court must examine:

wording;

transparency;

circumstances;

mandatory law;

nature of the service;

whether the term removes the provider's core obligations.

24. Unfair Jurisdiction Clauses

Consider:

Consumer lives in France.
Exchange operates in Germany.
Contract says: "Exclusive jurisdiction: Singapore."

Consumer-protection rules may restrict the effectiveness of such a clause.

The principles developed in:

Pannon GSM

Océano Grupo

Mostaza Claro

are relevant to the assessment of consumer contractual terms.

25. Arbitration Clauses

Crypto exchanges frequently use arbitration clauses.

A consumer may challenge:

mandatory foreign arbitration;

expensive arbitration;

distant arbitration;

foreign governing law;

combination of arbitration and foreign jurisdiction.

Soleymani v Nifty Gateway demonstrates how consumer objections to arbitration can arise in digital-asset contracts. (Bailii)

26. Misleading Advertising

A crypto exchange may advertise:

"Your crypto is completely safe."

or

"Withdraw anytime."

If the actual service operates differently, the consumer could potentially raise:

misrepresentation;

unfair commercial practices;

breach of contract;

regulatory claims.

MiCA also imposes specific requirements relating to investor protection and communications.

The regulatory environment is becoming more concrete: for example, Austria's FMA imposed a €70,000 fine on Bitpanda GmbH in August 2026 for MiCA breaches concerning a crypto-asset white paper and marketing communications. That is a regulatory enforcement action, not a private compensation judgment, but it illustrates the increasing regulatory scrutiny of crypto-asset providers. (fma.gv.at)

27. Crypto-Asset Custody and Insolvency

One of the greatest consumer concerns is:

What happens to my crypto if the exchange becomes insolvent?

MiCA requires client crypto-assets held in custody to be legally and operationally segregated from the CASP's own estate, subject to applicable law. The objective is to protect client assets from claims by the provider's creditors. (ESMA)

This represents a major shift from simply treating cryptocurrency balances as ordinary unsecured contractual claims.

28. Third-Party Custodians

An exchange may outsource custody.

Suppose:

Consumer → Exchange A → Custodian B

If the assets disappear, the legal question becomes:

Who is responsible?

MiCA Article 75 regulates the use of other authorised CASPs for custody and requires information to clients about such arrangements. (ESMA)

The consumer may therefore need to examine:

the exchange contract;

custody arrangement;

outsourcing agreement;

wallet records;

transaction history.

29. Wrong Wallet Address

Suppose the consumer accidentally sends:

10 ETH

to the wrong blockchain address.

The consumer then claims:

"The exchange should compensate me."

This is not automatically an exchange liability.

The court would examine:

who entered the address;

whether the exchange warned the customer;

whether address verification was available;

whether the exchange incorrectly executed the instruction;

whether the blockchain transaction was technically irreversible;

whether the provider was negligent.

ESMA has specifically highlighted the need for CASPs to have clear policies concerning liability for unauthorised or incorrectly initiated/executed transfers. (ESMA)

30. Cybersecurity

Crypto exchanges have heightened cybersecurity responsibilities because:

private keys can control assets;

blockchain transfers may be irreversible;

accounts can be accessed remotely;

phishing attacks are common;

smart-contract interactions can create irreversible consequences.

MiCA's custody regime specifically requires policies designed to minimise losses arising from fraud, cyber threats and negligence. (ESMA)

31. Data Protection

A compensation dispute may also involve GDPR.

An exchange processes:

identity documents;

addresses;

transaction history;

wallet addresses;

IP addresses;

financial information.

Potential disputes can concern:

unlawful disclosure;

excessive retention;

cybersecurity breach;

access requests;

deletion requests.

However, GDPR compensation is legally distinct from compensation for cryptocurrency price losses.

32. Cross-Border Jurisdiction

Crypto exchanges are inherently international.

Example:

Consumer: France
Exchange: Cyprus
Custodian: Germany
Blockchain: decentralised
Bank: Netherlands
Customer's loss: €200,000

The court may need to determine:

where the consumer is domiciled;

where the provider is established;

whether the provider directed activities to the consumer's country;

which contract is involved;

which law applies;

whether a jurisdiction clause is enforceable.

Ang and Payward v Chechetkin demonstrate the importance of consumer status in online cryptocurrency disputes. (Bailii)

33. Rome I and Consumer Contracts

Rome I generally protects consumers by providing special rules for consumer contracts.

The important issue is whether the exchange's activity was directed toward the consumer's country.

A foreign governing-law clause therefore does not necessarily eliminate all mandatory protections available to the consumer.

The recent FIBO Markets judgment illustrates the CJEU's continued attention to the boundary between consumer-contract rules and financial instruments. (Curia)

34. Compensation for Emotional Distress

A crypto customer might claim:

"The exchange's conduct caused severe anxiety and distress."

Whether this is compensable depends heavily on national civil law and proof.

The recent French N26/Bitpanda dispute is useful because the court provisionally recognised moral damage arising from the misleading handling of information concerning the account block, while refusing to award the claimed material loss at the interim stage. (Cour de Cassation)

35. Material vs Non-Material Damage

Material damage

lost crypto;

lost funds;

transaction fees;

proven consequential financial losses.

Non-material damage

distress;

uncertainty;

reputational harm;

other legally recognised non-pecuniary injury.

The availability and calculation of non-material damages varies significantly among European jurisdictions.

36. Burden of Proof

A consumer generally needs to establish the essential elements of the claim.

For example:

Customer must show

contractual relationship;

relevant obligation;

breach;

loss;

causation.

The exchange may then rely upon:

customer fault;

security breach caused by customer;

force majeure;

blockchain failure outside its control;

regulatory obligation;

contractual limitation.

MiCA's specific rules can alter the practical analysis for regulated custody providers.

37. Evidence in Crypto Claims

Useful evidence includes:

account statements;

wallet addresses;

transaction hashes;

screenshots;

order history;

emails;

customer-service communications;

terms and conditions;

timestamps;

blockchain explorer records;

KYC records;

security notifications;

withdrawal requests;

regulatory correspondence.

Because blockchain records are timestamped and technically verifiable, they can be important evidence of:

ownership/control;

transfer;

timing;

quantity;

destination.

38. Limitation of Liability

An exchange might state:

"Our maximum liability is €100."

Such a clause must be tested against:

mandatory national law;

EU consumer law;

MiCA;

nature of the breach;

whether the clause concerns essential obligations;

whether negligence or intentional misconduct is involved.

A standard contractual clause cannot automatically defeat mandatory statutory liability.

39. Regulatory Breach vs Private Compensation

This distinction is extremely important.

Suppose a regulator fines an exchange €1 million.

That does not automatically mean:

Every customer receives compensation.

A regulatory sanction and private civil damages are different legal mechanisms.

The consumer may still need to prove:

individual loss;

breach;

causation;

entitlement to compensation.

The Austrian FMA's 2026 Bitpanda sanction illustrates this distinction: the penalty was regulatory and concerned MiCA compliance, rather than being an individual customer compensation award. (fma.gv.at)

40. Direct Compensation Routes

A consumer may potentially pursue:

Route 1 — Contract claim

Exchange breached its agreement.

Route 2 — Tort/delict

Exchange acted negligently.

Route 3 — Consumer claim

Unfair term or misleading practice.

Route 4 — MiCA complaint

Complaint to the CASP and competent authority.

Route 5 — ADR

Where an applicable consumer dispute-resolution mechanism exists.

Route 6 — Civil court

Claim for restitution/damages.

41. Example Problem

Facts

A German consumer keeps:

€100,000 + 2 BTC

on a European crypto exchange.

The exchange experiences a cyberattack.

The 2 BTC disappear.

The exchange says:

"Our terms exclude all liability for hacking."

Legal analysis

Step 1

Determine whether the exchange provided custody.

Step 2

Determine whether MiCA applies.

Step 3

Examine the custody agreement.

Step 4

Examine security procedures.

Step 5

Determine whether the incident was attributable to the CASP.

Step 6

Examine the liability exclusion.

Step 7

Apply consumer unfair-term rules.

Step 8

Calculate the statutory/contractual loss.

Step 9

Determine the relevant valuation date.

Step 10

Determine whether restitution in BTC or monetary compensation is appropriate.

42. Example — Account Freeze

Facts

A French consumer has:

€200,000 of Bitcoin

on a platform accessible through a banking application.

The customer cannot sell Bitcoin for three months.

Bitcoin's price increases during the period.

The customer claims:

€50,000 lost profit.

Legal questions

The court would need to examine:

who actually controlled the crypto orders;

why the account was frozen;

whether the freeze was legally required;

whether the exchange breached the contract;

whether the customer could have mitigated the loss;

whether the €50,000 is sufficiently certain;

what valuation methodology applies.

The recent N26/Bitpanda French case demonstrates why identifying the entity actually responsible for the crypto transaction is critical. (Cour de Cassation)

43. Case-Law Summary Table

44. Most Important Principles

Principle 1

A cryptocurrency investor can qualify as a consumer even when making speculative investments, depending on the circumstances. Ang is particularly important. (Bailii)

Principle 2

A crypto exchange can be treated as a provider of contractual services.

Principle 3

Bitcoin exchange services have been recognised by the CJEU as services for EU VAT purposes. Hedqvist is the leading authority. (Legal Guide)

Principle 4

MiCA now provides specific obligations concerning crypto custody and client protection.

Principle 5

A CASP providing custody can be liable for loss attributable to it, subject to the MiCA liability framework. (ESMA)

Principle 6

Client crypto-assets must be segregated from the provider's own assets under the MiCA custody framework. (ESMA)

Principle 7

Consumers must have access to an internal complaints procedure free of charge. (ESMA)

Principle 8

Standard exchange terms can be challenged under European unfair-terms principles. (EUR-Lex)

Principle 9

Foreign arbitration and jurisdiction clauses are not necessarily immune from consumer-law scrutiny, as illustrated by Soleymani. (Bailii)

Principle 10

Crypto compensation requires careful identification of the actual loss and valuation date.

45. Major Litigation Categories

European crypto-exchange compensation litigation can therefore be divided into:

Unauthorised withdrawal claims

Crypto theft claims

Hacking claims

Account-freezing claims

Withdrawal-delay claims

Incorrect execution claims

Wrong-wallet claims

Custody claims

Insolvency claims

Unfair-term claims

Misrepresentation claims

Market-manipulation claims

Fee disputes

Liquidation disputes

Stablecoin claims

Token-delisting disputes

Data-breach claims

Cross-border jurisdiction disputes

Arbitration disputes

Damages-valuation disputes

46. Conclusion

Crypto-exchange consumer compensation law in Europe is developing from a combination of traditional civil law, EU consumer law and the newer MiCA framework.

The most useful direct crypto authorities include Ang v Reliantco, Payward v Chechetkin, Soleymani v Nifty Gateway, and the recent French N26/Bitpanda litigation. Hedqvist supplies the foundational EU classification of Bitcoin exchange services, while FIBO Markets illustrates the CJEU's continuing approach to cross-border consumer financial contracts. (Bailii)

The most important modern development is MiCA. For regulated custody services, it expressly addresses:

custody → segregation → security → complaints → return of assets → provider liability. (ESMA)

The central legal question in a compensation action is therefore:

Was the consumer's loss caused by a failure attributable to the crypto-asset service provider, and what remedy does the applicable civil, consumer and MiCA framework provide?
