The safest way to compare a crypto-friendly account is to identify the legal entity holding your money, then follow the custody chain. A deposit at an insured bank, a safeguarded e-money balance, cash held by an exchange, and a cryptoasset balance can look similar in one app but have completely different protection. In the United States, eligible deposits are generally covered by the Federal Deposit Insurance Corporation (FDIC) up to $250,000 per depositor, per insured bank and ownership category; cryptoassets are excluded. In the United Kingdom, eligible deposits can qualify for Financial Services Compensation Scheme (FSCS) protection up to £120,000, while France’s cited regime uses €100,000 under the Fonds de Garantie des Dépôts et de Résolution (FGDR). None of these schemes insure the value of cryptocurrency itself.
This comparison separates banking status, fiat custody, crypto functions, fees, transaction limits and failure protection for Mercury, Coinbase, Revolut and Monzo. Product terms vary by country and change frequently, so confirm the serving entity and the fee or limit displayed in your account before sending funds.

What “crypto-friendly” actually means
“Crypto-friendly” is a marketing description, not a legal category. An account may support exchange wires without allowing cryptocurrency trading, or it may offer in-app trading while keeping the crypto service outside the bank’s regulated deposit business. Start with three questions: Who is your contractual provider? Where is fiat cash held? Which entity controls the crypto wallet or trading service?
| Provider structure | What you receive | Protection question |
|---|---|---|
| Chartered or licensed bank | A bank deposit account, with possible exchange transfers and card or wire services | Is the exact bank insured, and is the balance an eligible deposit? |
| Fintech using partner banks | An app and account interface; partner banks actually provide banking services | Which partner holds the funds, how is your balance titled, and are records sufficient for pass-through coverage? |
| Crypto company or exchange | Trading, custody, deposits and withdrawals; sometimes a cash balance | Is cash segregated or pooled, and does any deposit-insurance scheme apply? Crypto balances themselves are normally outside bank-deposit insurance. |
The fiat path matters as much as the app’s features. A direct bank deposit is legally different from safeguarded electronic money or pooled custodial cash. A crypto withdrawal also introduces blockchain-network fees, address risk and risk-based limits that do not apply to an ordinary bank transfer.
How deposit protection differs by jurisdiction
United States: FDIC covers eligible deposits, not crypto
The FDIC’s consumer guidance states that the standard limit is $250,000 per depositor, per insured bank and ownership category. The insurance applies to qualifying deposits held at an FDIC-insured bank; it does not insure assets issued by non-bank entities such as crypto companies. Digital currencies are specifically excluded. The limit is not a guarantee that every dollar shown in a crypto app is insured: the account must be at an insured bank, and ownership and records must satisfy FDIC rules.
On March 28, 2025, the FDIC said FDIC-supervised institutions may engage in permissible crypto-related activities without prior FDIC approval, provided they manage risks and comply with applicable law. Acting Chairman Travis Hill described the change as “turning the page on the flawed approach of the past three years.” This policy concerns what supervised banks may do; it does not convert cryptoassets into insured deposits.
United Kingdom: FSCS coverage for eligible bank deposits
Eligible deposits at a covered UK bank can receive FSCS protection up to £120,000 per person per bank under the current information cited here. The protection is for eligible deposits, not for the market value of cryptocurrency or for an investment product merely displayed alongside a bank balance.
Recommended Free Tools
Revolut announced on March 11, 2026 that Revolut Bank UK Ltd had become a bank. Its announcement says eligible deposits receive FSCS protection up to £120,000 per person, while crypto, commodities and stocks are supplied by different entities and are outside Revolut Bank UK Ltd’s FSCS protection. Monzo’s December 2025 FSCS information sheet likewise states £120,000 protection for eligible deposits and treats business accounts as one depositor. The Monzo material does not establish Monzo as a crypto-trading provider, so it is a banking benchmark rather than a crypto platform.
France: FGDR protection at the cited Revolut entity
Revolut’s French deposit information identifies Revolut Bank S.A. and FGDR protection of €100,000 per depositor for eligible deposits. Crypto and investment products are not deposits under that explanation. A customer moving between countries can therefore see a different protection limit and serving entity without changing the app’s branding.
Pass-through coverage for pooled cash
When a fintech or exchange pools customer dollars at one or more insured banks, coverage may be “pass-through”: each underlying customer can potentially receive the applicable per-depositor limit if records identify ownership and the regulator accepts the arrangement during a bank failure. It is not automatic. Check the provider’s custody disclosure, the named banking institutions, aggregation rules and the records needed to prove your share.
| Balance type | Possible scheme | What is not covered |
|---|---|---|
| Eligible U.S. bank deposit | FDIC, generally up to $250,000 per depositor, per insured bank and ownership category | Cryptoassets and balances that are not qualifying deposits |
| Eligible UK bank deposit | FSCS, up to £120,000 per person per bank in the cited 2025–2026 information | Crypto, commodities, stocks and other non-deposit products |
| Eligible French deposit at the cited Revolut entity | FGDR, €100,000 per depositor | Crypto and investment products |
| Pooled custodial cash | May receive pass-through treatment if records and regulator determinations support it | No guaranteed coverage for crypto; eligibility depends on structure |
Provider-by-provider comparison
Mercury: business banking for crypto startups
Mercury presents banking for cryptocurrency startups, with business cards, controls and wire functionality. Wires sent through the account include the business name, which can help exchanges such as Gemini and Coinbase identify and credit a business wire. That is an operational convenience, not a promise that an exchange will accept every transfer.
Mercury states that it is a fintech company, not an FDIC-insured bank. Banking services are provided through Choice Financial Group and Column N.A., both Members FDIC. Therefore, the relevant protection analysis is at the partner-bank level: determine where your funds are actually held, how the account is titled, whether balances are spread across institutions, and how the program handles records and limits. The cited material does not state a universal Mercury transfer fee or a fixed crypto withdrawal limit; expect terms to depend on the product, business profile and partner bank.
Coinbase: exchange-linked cash kept separate from crypto
Coinbase says it is not an FDIC-insured bank and that digital currency is not insured or guaranteed by the FDIC. U.S. customer dollar funds are pooled in custodial accounts at U.S. financial institutions and/or invested in permitted liquid instruments. When held as cash at an FDIC-insured bank or an NCUSIF-insured credit union, the structure is intended to allow a claim for pass-through coverage up to the applicable per-depositor limit, currently $250,000 in the cited disclosure.
Pass-through treatment depends on accurate records and the regulator’s determination in a receivership. Coinbase states that crypto balances themselves are not insured by FDIC, NCUSIF or SIPC. Keep the distinction visible in your records: a dollar cash balance and a bitcoin or other token balance are separate risk exposures even when they share one login.
Revolut: bank account plus a legally separate crypto service
Revolut’s terms require a Revolut bank account to use its crypto service, but define the cryptoasset account as a separate service. The service covers buying, selling, depositing, withdrawing and holding cryptoassets. In the cited European arrangement, Revolut states that crypto services are not protected by the European Deposit Guarantee Scheme.
Do these 3 things before closing this tab:
1Repair Windows errors before they cause bigger problems2Scan for outdated or missing drivers - takes under a minute3Clear out junk files and repair common Windows errorsRevolut publishes a concrete fair-usage example for personal plans. Standard customers pay a 1% fee on monthly combined exchange activity above £1,000; Plus customers pay 0.5% above £3,000. Premium, Metal and Ultra plans have no fair-usage fee in that schedule. Crypto custody and deposits are listed as free. These thresholds and rates are plan- and market-specific examples, not a worldwide price promise; use the fee display in your app before confirming an order.
Crypto withdrawals have daily and monthly limits that reset on rolling periods. Revolut says limits can be adjusted using account activity and risk factors, and the applicable amount appears when you enter a withdrawal. A displayed, dynamic limit is therefore more authoritative than an old screenshot or a generic bank-transfer cap.
Monzo: conventional UK banking benchmark
Monzo’s December 2025 information sheet states that eligible deposits are protected up to £120,000 per depositor per bank and that a business account is treated as one depositor. The material does not establish Monzo as a crypto-trading provider. Use it to benchmark ordinary UK deposit protection, not as evidence that crypto purchases or external-wallet withdrawals are supported or insured.

What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
- Plan or subscription fee: a monthly account tier can change exchange allowances and fair-usage thresholds.
- Exchange fee or spread: the quoted price can include a spread even when a separate commission looks low.
- Fair-usage surcharge: Revolut’s cited examples add 1% above £1,000 on Standard and 0.5% above £3,000 on Plus during a monthly period.
- Bank transfer or wire fee: the sending bank, receiving bank or intermediary may charge separately.
- Network fee: a blockchain withdrawal can incur a network charge that changes with congestion.
- Third-party fee: an exchange, correspondent bank or payment processor can deduct its own amount.
Ask whether a quoted allowance is monthly, rolling, one-time or risk-based. “Free custody” does not mean a free sale, conversion, bank wire or blockchain withdrawal.

Bank transfers often have published daily limits, while crypto platforms may combine deposit, withdrawal, transaction-size and compliance limits. Revolut’s crypto withdrawal limit is shown at the point of withdrawal and can change with account activity and risk factors. Coinbase and Mercury may also apply customer- or transaction-specific controls; the cited disclosures do not provide one universal number.
Before a large transfer, complete identity verification, confirm the beneficiary name, send a small test amount and retain the confirmation. A transfer that is below a published cap can still be delayed if the receiving institution cannot match the sender, the account is newly opened, or a compliance review is triggered.
A safer workflow for funding an exchange or withdrawing to a wallet
- Identify the serving entity. Read the account’s legal terms and note the bank, fintech, exchange and country entity separately.
- Classify the balance. Mark it as an insured bank deposit, safeguarded or custodial fiat, or cryptoasset. Do not treat an in-app dollar figure as proof of FDIC, FSCS or FGDR coverage.
- Check the destination instructions. Use the exchange’s exact beneficiary name, reference code, routing details and supported currency.
- Review the live price and fees. Capture the spread, commission, fair-usage status, network fee and any third-party charge before authorizing.
- Verify limits in the app. For dynamic crypto limits, enter the withdrawal screen and record the amount shown at that moment.
- Send a test transaction. Confirm that the bank wire or blockchain transfer arrives before moving the full amount.
- Reconcile records. Save statements, transaction IDs, wallet addresses, fees and the entity that held each balance. These records can matter for tax reporting and for proving ownership in a pass-through claim.
Common failure scenarios and what to do
The exchange rejects a bank wire
Check that the sender name matches the exchange account, the required reference is present and the currency and beneficiary details are correct. A business account may be required for a corporate exchange account; Mercury’s business-name wires can help matching, but acceptance remains the recipient’s decision.

Use the live limit displayed in the withdrawal flow. Rolling-period counters, account activity and risk controls can reduce the amount without a published policy change. Split the transfer only if the platform permits it and the extra network fees are acceptable.
A fintech fails and you assumed the balance was insured
Determine whether the money was an eligible deposit at a named insured bank, pooled custodial cash with possible pass-through treatment, or a crypto balance. Gather statements showing the underlying bank, account title and your ownership. Deposit schemes do not reimburse a fall in token value.
You need a business account for frequent exchange wires
Choose a provider that supports your entity type, documents the sender name clearly and explains partner-bank custody. Compare wire pricing, approval workflow, user controls and country eligibility before opening the account; a consumer app with attractive trading fees may not satisfy business banking or accounting requirements.
Which structure fits your use case?
| Your priority | Structure to evaluate first | Critical check |
|---|---|---|
| Maximum clarity about deposit insurance | A directly insured bank account | Confirm the bank’s insurance status and that the product is an eligible deposit. |
| Frequent company wires to exchanges | A business fintech with documented partner banks, such as Mercury’s model | Review partner-bank custody, sender-name handling, wire limits and records. |
| Trading and wallet withdrawals in one app | An exchange or fintech crypto service, such as Coinbase or Revolut | Separate cash protection from crypto custody; read dynamic limits and withdrawal fees. |
| Conventional UK cash management | A bank such as Monzo | Verify FSCS eligibility; do not infer crypto support from deposit protection. |
Use the provider’s current legal terms for the country where you reside, not a generic global webpage. A name, logo or “crypto-friendly” label cannot answer the insurance question; the custody chain and account records do.
