Fiat deposit

A fiat deposit is a transfer of money, not a purchase: the euros or dollars sit in your exchange balance until you place an order. Bitstamp caps fiat deposits at $10,000 for the lifetime of a Level 1 US account and holds ACH funds seven days before you can withdraw. Plan the funding step before the trade, because that is where a first purchase usually stalls.

How it works

A fiat deposit passes four gates before the money is yours to spend, and each one lives in the exchange's terms rather than on its pricing page.

The first gate is the name on the sending account. Bitstamp's Terms of Use state that it does not accept fiat currency deposits from third-party bank accounts, that the name on your linked bank account must match the name verified on your Bitstamp account, and that a wire received from a third-party account will be rejected and returned immediately. Sending from a spouse's account, a company account or a friend's account is not a slow deposit. It is a returned one.

The second gate is where your bank account lives. Bitvavo tells residents of thirteen further territories, among them Curacao, Aruba, Martinique and Madeira, that they can open an account but must supply "a valid ID or IBAN from one of the fully supported SEPA countries" to complete identity verification and use all payment methods, and that without one "certain features of the Bitvavo service will not be available". The account opens. Verification, and with it the payment methods, is the part that does not.

The third gate is your verification level. Bitstamp's US terms publish the table outright: at Level 1 the fiat deposit ceiling is $10,000 and crypto withdrawals are unavailable, at Level 2 both are unlimited, and the Level 1 limits stay in force for the lifetime of the account until Level 2 is completed.

The fourth gate is settlement. Bitstamp applies a standard seven-day hold on ACH funds awaiting settlement, warns that a wire payment generally arrives within a week but may take up to two weeks depending on your financial institution, and withholds assets bought with a card or another instant payment method from withdrawal for up to fourteen days. Money showing in your balance is not always money you can move.

One sentence in the same document deserves a second reading: "Your Account, once funded, does not and will not earn interest."

Why this matters when you buy bitcoin

A fiat deposit, rather than the trading fee, is what decides whether a first purchase happens at all, which is why it is recorded per exchange here: 52 of the 63 exchange records carry a deposit note saying what funding costs and which rails are free.

Those notes are where the money actually is. The Bitstamp record here says SEPA deposits are free while international wires and card purchases carry fees. The Bitvavo record says SEPA deposits are free and iDEAL is free for Dutch residents with a five euro minimum. Bitvavo's base tier charges 0.15 percent maker and 0.25 percent taker, so on a 200 euro first order the trading fee is 50 cents and the funding rail is the only line left worth arguing about.

Which rail you get is set by your address rather than your preference. Bitvavo's own Countries page lists 25 countries, and a SEPA bank transfer, PayPal, a credit card and Apple Pay run on all 25 rows; the local bank rails reach three of them, iDEAL and Wero in the Netherlands, Bancontact in Belgium, EPS and Giropay in Austria. Its help centre closes the outer ring plainly: "At this time, Bitvavo only supports users who reside within the SEPA zone." Of the 231 country guides on this site, 32 list a SEPA bank transfer among the locally available rails, which is why the funding question looks nothing alike in Lagos and in Lisbon.

Then there is what happens to the money after it lands. Bitstamp's terms say it does not hold your fiat itself: the money goes to one or more Banking Providers, held on trust for you, commingled with other customers' funds in the same currency, giving you a pro rata entitlement rather than an account of your own. The same terms say that fiat "will not be protected by the UK Financial Services Compensation Scheme or other applicable compensation or deposit guarantee schemes" if the exchange becomes insolvent or defaults. Deposit what you are about to spend, buy, then withdraw the coins. An exchange balance is a waiting room.

Hungary, where euro deposits stopped while withdrawals kept working

Bitvavo's Hungarian customers went on withdrawing euros and moving crypto right through a suspension that had stopped their euro deposits, buying and selling, which shows exactly where a deposit sits in the stack.

Hungary's National Assembly passed Act XXXVIII of 2026 by 143 votes to 46 with one abstention, repealing a local mandatory crypto-asset conversion validation regime that conflicted with MiCA. Bitvavo then restored full functionality to existing Hungarian clients, buying, selling and euro deposits included, and set September 7, 2026 as the date new Hungarian residents could be onboarded again. The instructive line is the operator's own note on what never stopped: "Withdrawals and crypto transfers were never restricted during this period and remain fully available."

The shape of that is worth remembering. Every function that took money or new customers in was gated, and every function that let assets out was not. Anyone whose coins were already in self-custody was untouched by any of it.

Fiat deposit vs on-ramp

A fiat deposit moves money into an account; an on-ramp turns money into bitcoin, and a card payment can be the second without ever looking like the first. Bitstamp's terms keep the two in separate clauses: "Funding Your Account" covers wire and ACH deposits, while "Placing an Electronic Purchase" covers cards, Google Pay and Apple Pay, buying the asset in one step and locking it against withdrawal for up to fourteen days. The difference shows up when something goes wrong, because a wire sent from the wrong name is rejected and returned to your bank, while the same terms make every completed purchase final and credit fiat back to you only where the exchange itself failed on a technical issue or a price move.

Fiat deposit vs custodial wallet

A fiat deposit and the bitcoin you buy with it are held under two different legal arrangements at the same exchange, even though one screen shows them side by side. Bitstamp holds the fiat itself, on trust, at Banking Providers it selects, commingled with other Members' money and yours only pro rata. For the coins its terms say the opposite: it stores no Virtual Assets directly, and acting as your agent it appoints a third-party custodian whose services "will be provided on terms that apply directly between the custodian(s) and you", adding that Bitstamp "does not directly provide, charge for and is not responsible for, custodian services". Two counterparties, two failure modes, one balance page. The only holding on that page with neither arrangement behind it is the one you have withdrawn to a wallet whose keys you hold.
