Bank, exchange, wallet, cashier
iDEAL and crypto, and the route euros take before a casino sees them
A bank transfer and a coin transfer live in two separate systems. Between them sits a platform that turns euros into coins, and that step decides most of the costs, the rate and the paperwork you will want later.

iDEAL and crypto meet at one point only: the moment euros from a Dutch bank account buy coins on a platform that sells them. The casino is not part of that step. A crypto cashier receives coins on a blockchain address, and whatever happened before, a bank payment, a card purchase or coins already held, is invisible to it.
This guide follows the money along that route, from bank to exchange, from exchange to your own wallet and from wallet to a deposit address. It does not say which casino accepts which payment method, and it names no platform as a place to buy; the aim is to show what each step costs and what to write down.
Why a crypto cashier thinks in coins
A casino that works with crypto publishes addresses per coin and per network. What reaches that address is a number of coins, confirmed by the chain, and that number is what the casino credits. Even when the balance is displayed in dollars or euros, the conversion happens inside the casino at its own rate, as the deposit guide describes.
That has a practical consequence. The euro amount you paid at the start is not what the casino sees. Between the two lie a purchase price, one or more fees and possibly a second conversion. Knowing each of them is the only way to understand later why €100 turned into a slightly different balance.
The route of iDEAL and crypto, step by step
1. Bank to platform. You buy coins on a broker or exchange that accepts euro payments. Many platforms offer iDEAL for topping up a euro balance or for a direct purchase. Before the first purchase, such platforms usually ask for identity documents of their own; this is separate from any check a casino may request later.
2. Euro to coin. The platform converts euros into the coin you pick. Here two kinds of cost appear: an explicit fee, shown as a percentage or a fixed amount, and the spread, the gap between the price at which the platform sells to you and the price at which it would buy back. Brokers that advertise no fee often earn through a wider spread.
3. Platform to your own wallet. Moving coins to a wallet you control, before sending anything to a casino, gives you a clear record and keeps the exchange account apart from gambling transfers. The platform charges a withdrawal fee in coins, and the network adds its own fee.
4. Wallet to casino. Only now does the casino address come in. Coin, network and, where needed, memo must match what the cashier shows. From here the rules of the casino's terms take over: minimums, wagering on the deposit, and the way money has to leave again.
Sending coins directly from an exchange to a casino saves one network fee, but it links the two accounts and can cause trouble when a casino pays back only to the source address. Rocketpot is a case in point: its cl. 11.1 (read on 2 September 2026) sends winnings back in the coin used and only to the originating wallet.
Euro and dollar stablecoins in iDEAL and crypto payments
Stablecoins aim to hold a fixed value against a currency. Most volume sits in dollar-based tokens such as USDT and USDC, which follow the US dollar. There are also euro-based tokens that follow the euro.
For someone who thinks in euros, the difference is real. A dollar stablecoin removes the swings of bitcoin, but the euro value of your balance still moves with the euro-dollar exchange rate. A euro stablecoin avoids that second movement, provided the cashier lists one at all. Whatever the choice, check that the casino lists the exact token and network before buying; a stablecoin the cashier does not support is of no use at that casino. The table of limits and caps on the withdrawal page is printed in the currency each operator uses, often USDT or dollars.
An illustration of costs, with assumed figures
The figures below are invented round numbers to show the arithmetic, not prices of any platform.
- You top up €200 by iDEAL; assume the platform charges no fee for that top-up.
- You buy a dollar stablecoin with an assumed 1.5% fee and a 0.5% spread; about €196 of value is left.
- You move the coins to your own wallet; assume a withdrawal fee equal to €1.
- You send them to the casino; assume a network fee equal to €0.50.
Roughly €194.50 of value arrives, before any conversion the casino itself applies. On the way back, similar layers repeat in reverse. Small fees add up once the route runs twice.
What to write down at each step
A short log saves a great deal of guessing later, for your own overview and for any dispute with a platform or casino:
- date and euro amount of the iDEAL payment, with the bank reference;
- coin, amount bought, price per coin and the fee the platform showed;
- the transaction ID of the move to your own wallet, with the fee;
- the transaction ID, address, network and memo of the deposit to the casino;
- the balance the casino credited and the rate it used, if shown.
Screenshots with a visible date help. Keeping records also makes it easier to see what gambling really costs over a month, which is a sound habit in itself; the page on setting limits and taking breaks has more on that. Questions about gambling winnings and Dutch tax are handled on a separate page about the tax on prizes.
