Where the cost of a deposit actually sits

Only one of the four common funding methods shows you its cost as a fee. On the other three it is inside the rate, which is why comparing published fees produces the wrong ranking.

A funding page can truthfully say "no fees" about the most expensive route on it. Nothing dishonest has occurred: the cost simply is not a fee, and no rule requires it to be presented as one.

The one where the number is the number

A direct bank transfer usually carries a visible flat fee, sometimes none at all for local transfers, and no currency conversion when you are funding in the currency you hold. The published figure is close to the whole cost.

This has an obvious consequence for how it ranks. A flat fee is a large proportion of a small deposit and a trivial proportion of a large one, so this route looks worst on small amounts and best on large ones. Any comparison that does not specify an amount is comparing nothing.

The exception is cross-border. A wire passing through correspondent banks can have deductions taken by intermediaries you never see, which means the amount arriving is less than the amount sent minus the fee you were quoted. Reconstructing where it went afterwards is difficult, and the fee you were shown was accurate about the part your own bank charged.

The requirement that catches people is unrelated to cost: most platforms require the sending account to be in the same name as the verified account. Transfers from a spouse's account or a business account are routinely returned, which takes days and sometimes costs a return fee.

The three where the cost is in the rate

Card funding, third-party payment providers and peer-to-peer trading share a structure: you are quoted a rate rather than charged a fee, and the cost is the distance between that rate and the mid-market rate at the same moment.

This is not concealment in any legal sense. It is a genuinely different pricing model, and it is standard across currency exchange generally. But it has a specific effect on comparison shopping: the number that would let you compare is not displayed anywhere, and computing it requires knowing the mid-market rate at the instant you were quoted.

Which produces the practical rule that replaces fee comparison entirely:

The only comparison that works

How much fiat left your account, and how much crypto arrived. Everything between those two numbers is the cost, whatever it was called and wherever it sat. Run this once, on a small amount, for each rail you might use. It takes one transaction and settles a question no funding page will answer.

What each route is, briefly

Card networks. Near instant, typically the most expensive of the four, with the cost in the rate. The complication worth knowing in advance is that some card issuers classify this merchant category as a cash advance rather than a purchase — which adds a cash advance fee and starts interest accruing from the transaction date with no grace period. That decision belongs to your issuer, not the platform, and is worth one call before the first attempt.

Third-party payment provider. A licensed payment institution handles the fiat leg while the exchange handles only the crypto leg. Minutes to hours, cost in the rate. Structurally this is the least stable route, because there is an additional independent business on it with its own risk appetite and commercial priorities, any of which can end the arrangement without reference to you or the exchange.

Peer-to-peer. Fiat moves directly between two users' bank accounts; the platform escrows only the crypto. Often the cheapest on paper and often the last route still working when others have gone. Its risk is of a different kind: the escrow protects the crypto side and cannot protect the fiat side. If funds you receive turn out to be the proceeds of a fraud, the sending bank may reverse or freeze the transfer after the crypto has been released, and your receiving account can be frozen pending investigation. An unusually favourable rate is a reason for caution rather than an opportunity.

The full classification by clearing route, and why the route determines the failure mode, is set out separately.

Speed, and why it is not a platform property

Settlement time is decided by the clearing system, not by how responsive the exchange is. An instant local payment scheme settles in seconds; an older batch system does not settle outside business hours at all, whatever anyone does.

Two consequences that are worth planning around rather than being surprised by. Weekends and public holidays are genuinely dead time on bank rails, and a Friday evening transfer is a Monday arrival in many systems. And the platform cannot make its bank clear faster — when support says the funds are not with them yet, that is usually accurate rather than evasive.

The other half of speed is the hold applied after arrival. Funds added by certain rails may be unable to leave for several days, because the incoming payment can still be reversed at the other end. That is the platform managing a real exposure, and it is a property of the rail you chose. If you intend to move funds out promptly, it belongs in the decision.

Reversibility changes who carries the risk

The four routes do not merely settle at different speeds. They reach different kinds of finality. A completed bank transfer is usually difficult to reverse without the recipient's cooperation. A card payment can be disputed through the issuer. A peer-to-peer payment may be frozen while a bank investigates the sender. Those are different legal and operational states even if the exchange screen labels all of them "completed".

This explains two behaviours that otherwise look arbitrary. Platforms hold some incoming funds before allowing withdrawal because they have delivered an irreversible asset against a payment that may still be reversed. They also insist that the sending account name match the verified account because a third-party payment has the same shape as several common fraud patterns. The rules are blunt because the platform cannot reliably judge intent one transfer at a time.

For the user, the practical answer is record-keeping. Keep the bank reference, the quoted rate, the amount sent, the amount credited and the time each status changed. If a transfer stalls between institutions, the exchange can see only its side and the bank can see only its side. You are the only party who can join the two records. A screenshot of a generic "processing" badge is much less useful than a reference number and the exact account names involved.

A comparison you can run with your own numbers

Before choosing a rail for a meaningful amount, write down five fields from the confirmation screen: the amount leaving your account, the amount of crypto or fiat that will arrive, the market mid-rate at that moment, every separately stated fee, and any hold before the funds can leave again. Do the same for the next-best route. This is not a calculator that needs a platform database; it is a small audit of the quote in front of you.

The comparison often changes once time is included. A route with the lowest visible cost may be poor if it locks the funds past the date you need them. A fast route with a higher spread may be rational for a genuine deadline. A route that is cheap in one direction may have no usable withdrawal path. There is no universal winner because amount, urgency, reversibility and the need to withdraw are inputs that belong to you rather than to the platform.

Repeat the exercise when the amount becomes materially larger or when you change country, currency or account level. Do not assume a small test proves the price of a later large transfer; proportional markups, flat fees and channel limits scale differently. The test proves that the route works. The confirmation screen for the later transfer still decides what it costs.

Choosing, in practice

Given all of the above, the decision reduces to four questions.

  1. How much, and how often? Flat fees favour large infrequent transfers; rate-based pricing is proportional and indifferent to size. This single question flips the ranking.
  2. How soon do you need it to settle? If the answer is now, the fast routes cost more and that is the trade being made rather than a mistake.
  3. Do you need it to leave again soon? Check the withdrawal side and any post-deposit hold before funding, not after. The set of available rails is not always symmetrical.
  4. What is your second route? Given how these rails fail — abruptly, because of a decision by a business you have no relationship with — knowing a fallback exists is worth more than a marginal saving on your primary one.

To see the four routes side by side with their clearing path, cost shape, speed and stability, the rail lookup covers them one at a time. It publishes no country availability list, for the same reason this page publishes no fee figures: that data is wrong within weeks and wrong in the direction that costs you money.
