Crypto Banks: A Sceptical Guide

"Crypto banking" is a marketing phrase, not a legal category. That is the single most useful thing to know about it, and almost every mistake people make in this corner of finance follows from not knowing it.

A bank is a defined thing. It holds a banking licence, it takes deposits, it is supervised, and in most developed markets its customers sit inside a deposit guarantee scheme with a published limit. A platform that lets you hold Bitcoin, earn a yield on a stablecoin and spend from a card is doing none of that, however closely the interface resembles a banking app. It may still be regulated — but regulated as something else, under a regime with different obligations and, critically, a different answer to the question "what happens to my money if this company fails".

This guide is about telling the categories apart.

Four different things wearing the same word

A crypto-friendly bank is an ordinary licensed bank that does not block payments to and from exchanges. Your money is a bank deposit, covered by whatever scheme covers that bank, and the crypto sits somewhere else entirely. The "crypto" part is a policy about which payments it will process — nothing more.

A licensed institution offering crypto services is a bank or investment firm that has added digital-asset custody or trading under its existing authorisation. Here the distinction inside the account matters enormously: cash held as a deposit may be scheme-protected; crypto held in custody is not a deposit and is not protected by any deposit scheme, regardless of how well it is safeguarded.

A crypto-asset service provider is a firm authorised specifically to provide crypto services — custody, exchange, transfers. It is supervised, it has obligations about how it holds client assets, and it is not a bank. No deposit guarantee applies to the crypto.

A non-bank platform with no relevant licence at all, offering yield, loans and cards. This is where most of the "crypto bank" branding lives, and where nearly all of the historical losses happened.

The interfaces are indistinguishable. The legal positions are not remotely comparable.

The question that separates them

Ask this, in these words: which legal entity holds this specific asset, under which authorisation, and what happens to it in that entity's insolvency?

A firm that can answer clearly, and point you to a public register you can reach without following its link, is in a different class from a firm that answers with the word "secure". Note that the answer can differ per asset inside one account — your euros and your Bitcoin may sit with different entities under different rules, in the same app, on the same screen.

Two comparisons make the stakes concrete. Under the EU's deposit guarantee regime the coverage level for the aggregate deposits of each depositor is EUR 100 000, and in the United States the FDIC states that deposits "are automatically insured to at least $250,000 at each FDIC-insured bank". No equivalent applies to a crypto holding anywhere. That is not a gap somebody forgot to close; the schemes cover deposits, and a crypto asset is not one.

Yield: where does it actually come from

The products advertised as "crypto savings" pay a return, and a return has to come from somewhere. There are only a few real answers, and they carry different risks:

• Lending your assets to borrowers, who pay interest. Your risk is their default, plus the platform's underwriting.
• Staking, where assets secure a blockchain network and earn protocol rewards. Your risk includes lock-up periods and protocol penalties.
• Deploying into automated protocols, where returns come from trading fees or incentives. Your risk includes code defects and the value of the incentive token.
• The platform's own balance sheet, paying a promotional rate to attract deposits. Your risk is the platform.

If a provider will not tell you which of these it is doing, that refusal is the answer. And a yield that is far above what the same risk earns elsewhere is not a discovery — it is a description of the risk being taken with your money.

We have deliberately quoted no rates anywhere in this article. Advertised yields on these platforms change frequently, differ by asset, tier and country, and a number copied into a guide is exactly what a reader acts on months later when it is no longer true. Read the rate on the provider's own page on the day you deposit.

Borrowing against crypto, honestly

Crypto-backed loans let you borrow cash against holdings you do not want to sell. The mechanism is straightforward and so is the danger: the loan is over-collateralised, and if the collateral's value falls past a threshold, the platform sells your collateral to protect itself. It does not need your permission, it does not wait for a recovery, and it can happen while you are asleep.

Sizing is the whole discipline. Two questions decide whether you should do this at all:

1. How far can this collateral fall before liquidation, and has it fallen that far before?
2. If it does, can I add collateral fast enough, from money I already have?

If the answer to the second is no, the position is too large. There is also a tax dimension — borrowing rather than selling is often chosen specifically for tax reasons, and whether that works depends entirely on your jurisdiction. That is a question for a qualified adviser in your country, not for a comparison site.

What good disclosure looks like

The last one matters more than people expect. Nearly every large failure in this sector was preceded by withdrawals slowing down.

The scam that lives next door

A significant share of what markets itself as crypto banking is not a risky product but a fraud, and the shape is consistent: the balance grows, small withdrawals succeed, and a large withdrawal triggers a fee you must pay in fresh money before your existing money is released. Regulated firms deduct costs from your balance. They do not require an inbound payment to permit an outbound one.

We cover the full pattern, and five relatives of it, in six cross-border scams to watch for. If you take one habit from this article, take that one: money never has to go in for money to come out.

The counter-argument to the sceptics

Being sceptical is not the same as saying no. Blanket avoidance has its own cost, and dismissing the whole sector means missing that supervised crypto-asset regimes now exist in several major markets, that custody standards at serious firms have improved substantially since the 2022 failures, and that for someone who already holds digital assets, a supervised custodian is a genuine improvement on a private key in a drawer.

The argument of this article is narrower than "avoid". It is: know which of the four categories you are dealing with, never let the word "bank" do work that a licence has not done, and size the position to what you can lose.

For the wider context, see earn and borrow accounts and, on the banking side of the seam, why banks block crypto transfers.

General information, not financial, legal or tax advice. Crypto assets are volatile and are not covered by deposit guarantee schemes; regulation, eligibility and product terms vary by country and change. Verify every figure with the provider and your own regulator.
