Note on costs
USD fees and processing: where the cost of a dollar hides
Between a dollar in a bank and a coin at an operator there are up to four layers of cost, and each is charged by a different party. Operators tend to speak about the one they control and leave the others to the reader.
This note names the layers and attaches the few figures that operators print. It prints no live rate and no network fee.
What does a card purchase of coins cost?
BetFury's documentation gives a worked example. Buying USDT with dollars carries a fee that the page puts at 14.6% for a purchase of $30 and 5.7% for $100, and concludes that one large deposit costs less than several small ones. The page is undated and the figures are an illustration, but the shape holds for any provider that charges a fixed part: the smaller the purchase, the larger the share.
Does the operator add its own fee beyond conversion and network cost?
At Duelbits, by its own statement, nothing: it says it charges no platform fees on deposits or withdrawals, and that the only costs are network fees paid to the network. Rollbit says the same for deposits and adds that the sender pays the on-chain cost. Sportsbet.io says it covers the withdrawal fee. All three are statements from the operators' pages, and none is a promise about next month.
Where is the conversion cost?
In the rate. None of the pages we read prints a spread between the rate used to convert a deposit and a market rate. That does not mean there is none. It means the cost of conversion is invisible unless you compare the amount you send with the amount you receive, which is why the cashier's confirmation figure is the only measure.
Why are timings tied to a stage?
Because the same number appears at different moments. BetFury says in its documentation that a deposit is credited automatically and may in rare cases take 24 to 72 hours, and says on its front page that a withdrawal can take up to 24 to 72 hours while a risk department audits it. A time quoted for one stage is not a time for the whole trip.
How do you measure the total cost yourself?
Compare two numbers: what left your bank or wallet, and what the cashier shows as credited, both in the same unit. The difference is the sum of every layer above, and it is the only measure that includes the conversion. Do it once with a small amount and once with a larger one, and the gap between the two shares tells you how much of the cost is fixed.
A small first deposit is sensible for other reasons and costs more per dollar for this one. Weigh the two before choosing the amount.

| Is a big deposit always cheaper? | Per dollar, usually, where a provider charges a fixed part. BetFury's example shows a smaller share on a larger purchase. |
