Bitcoin: the oldest coin, with the slowest blocks
By Kristaps Birznieks · updated October 2026
Bitcoin is the first and best-known cryptocurrency. In cashiers that offer crypto at all, it is often listed first — but it is not the fastest or cheapest coin to move. This page explains how Bitcoin payments work in practice; it does not claim that any particular operator accepts them.
The set of methods and limits depend on the account and the operator — check the cashier to see what your account actually offers.
Technical basics
- Block time. A new Bitcoin block is produced roughly every 10 minutes on average. Crediting time depends on how many confirmations the operator requires, so a deposit can take from about ten minutes to an hour or more.
- Addresses. Bitcoin addresses usually start with "1", "3" or "bc1". If the address in the cashier looks different, check that you selected the right coin.
- Fees. The network fee is not fixed. It depends on how busy the network is and on how quickly you want the transaction confirmed. In busy periods it can be noticeably higher.
Depositing step by step
- Choose Bitcoin in the cashier and copy the address or scan the QR code.
- In your wallet, enter the amount and check the first and last characters of the address.
- Choose a fee level; a very low fee can leave the transaction waiting for a long time.
- Send, then wait for the confirmations the operator requires.
- After confirmation, the amount appears in your balance — often converted into the account currency.
Withdrawing
You give your Bitcoin address for the withdrawal. Before the first one you will usually need to verify your identity with an ID card or passport. Some operators require withdrawals to go to the same address you deposited from. The time depends on the operator's processing and the network.
Price risk
Bitcoin's price can move sharply within a single day. If you deposit in Bitcoin into a euro account, the conversion happens at crediting. If you withdraw in euro terms and receive Bitcoin, the value can change while the funds are in transit or sitting in your wallet. Bitcoin is therefore a poor place to "store" winnings: it adds a second volatile element to an activity that is already risky.
Safety checks
| Check | Why |
|---|---|
| Address only from the cashier | Fake addresses circulate in chats and emails |
| Correct coin and network | Bitcoin cannot be sent to another coin's address |
| Small test amount first | A mistake costs less |
| Operator in a licence register | Without a licence there is nowhere to complain |
Bitcoin and session discipline
Crypto payments are fast to send, which, as with cards, means impulse risk. If you play live tables or bet in play, decide your budget in euro rather than in coins — it is much easier to see how much you have actually spent. General crypto concepts are on crypto, payouts on withdrawals, and the overview of methods in payments. The maths of the tables you might be funding is on table games.
