Cryptocurrencies are a very fast and secure payment method for deposits and withdrawals at your favorite casino

Cryptocurrencies offer speed, stable coins like USDT/USDC, and transparent transaction tracking. In this article, we’ll show you what to know before your first deposit: how to choose the right chain, what fees to expect, and what to watch for so your transaction is successful.

Popular payment methods

What are cryptocurrencies as a payment method?

A cryptocurrency is a digital currency stored on a blockchain. A blockchain (often referenced simply as a chain) is a ledger that verifies and records transactions. When depositing at a casino, the cashier asks you to choose a currency (e.g., USDT or ETH) and a chain (e.g., TRC20 or ERC20). You can think of the chain as a „payment route“, similar to choosing a transfer type at a bank. The casino will show you an address (like an account number) and for some currencies also a memo/tag (a short identifier, similar to a payment reference). Send the payment from your wallet or exchange to the given address on the same chain, and after the required number of confirmations the amount will be credited to your gaming account.

Key to success: same currency, same chain, correct address, and memo/tag if required.

How long do crypto deposits and withdrawals take?

Most cryptocurrency transactions are fast, especially compared to standard fiat transfers. It’s usually a matter of minutes, but it depends on the chain, current network load, fees paid, and how quickly a given brand processes incoming payments. Some systems credit the deposit immediately after the required number of confirmations, others may have a short delay due to internal checks. Withdrawals are often slower than deposits due to account checks, KYC, and manual approval.

The indicative times below assume normal network load. Crediting to your gaming account can take longer if the platform uses internal checks or a higher number of confirmations.

Chain / currency

Min. number of confirmations

Approximate time*

Note

TRON (TRC20) – USDT/TRX

1–2

~1–5 min

Fast and cheap; common for USDT deposits

BNB Smart Chain (BEP20) – USDT/BNB

1–5

~1–5 min

Low fees

Ethereum (ERC20) – USDT/USDC/ETH

1–15

~1–15+ min

Time and cost fluctuate with chain load

Bitcoin (BTC)

~0,5–2 min

Very low fees, very high speed

*Approximate time: the time a chain typically takes to confirm a transaction.

Now that you know what a currency and a chain are and how long confirmation takes, let’s walk through the deposit process from selecting a currency to crediting.

How crypto deposits work step by step

Although the process may seem complex, the opposite is true. You choose a currency and chain, enter the amount, copy the address (or scan the QR code), and send the payment from your wallet or exchange. After the required number of confirmations, the deposit is credited.

1) Choose a currency and chain

  • In the Deposits/Withdrawals section, choose the desired currency (e.g., USDT, BTC, or ETH). Some currencies will also display chain icons (e.g., TRC20 / ERC20 / BEP20 for USDT). Select exactly the chain where you hold the funds to deposit.
  • Tip: USDT on TRC20 ≠ USDT on ERC20. It’s the same currency but a different „payment route“.

2) Enter the deposit amount

  • Set the amount (preset values or your own).

3) The address is displayed

  • The platform shows you the deposit address and selected chain; often also a QR code (convenient if your wallet is on mobile).
  • The address is unique to the given chain (e.g., 0x… on ERC20, T… on TRC20, bc1… on BTC).
  • Always copy the address—do not retype it manually.
  • Some systems generate one-time addresses with a time limit. If it expires, generate a new one.

4) Send from your wallet/exchange

  • In your wallet/exchange, select the same chain, paste the address, add a memo/tag if needed (see below), and send. We recommend starting with a small test transaction and only then sending the rest.

5) Chain confirmation and crediting

  • The chain verifies the transaction (see the table in the previous section). After the required number of confirmations, the platform’s system credits it. Some brands perform internal checks, so crediting may take a little longer.

6) Special cases: memo/tag (XRP, etc.)

  • For Ripple (XRP) and Stellar (XLM), a destination tag / memo is mandatory. It assigns the payment to your account because multiple users share one address.
  • Missing or incorrect tag = payment not credited (must be resolved with support; not always reversible).
  • Some exchanges may also require a tag/memo for BNB deposits.

7) Quick pre-send check

  • Currency and chain: must match what the platform requires (e.g., USDT-TRC20).
  • Address: paste by copying (check first/last characters).
  • Tag/memo: fill it in if required for the currency (XRP/XLM).
  • Test transaction: send a small amount first, then the rest.
  • Explorer: after sending, check the transaction status via the TX ID (crediting may only appear after the set number of confirmations).

Where you can use crypto

Today, most gaming platforms offer a wide selection of cryptocurrencies for deposits and withdrawals. At the best casinos and sportsbooks, it’s practically standard. Brands with a rich choice of cryptocurrencies include platforms like Rabona, LibraBet, and Sportuna. Some casinos are even crypto-only and do not offer traditional fiat methods at all. The availability of specific currencies and chains varies by platform, so always follow the cashier instructions on the given site.

In practice, you’ll encounter several mainstays. The overview below helps you quickly check which currencies and chains are most common across gaming sites.

Supported currencies and chains

Below are the currencies and chains you’ll most often see offered at casinos and sportsbooks. The actual list may vary by brand.

Currency

Most common chains

Note

USDT (Tether)

TRC20 (TRON), BEP20 (BNB Smart Chain), ERC20 (Ethereum)

Stablecoin pegged to USD (1 USDT = 1 USD).

BTC (Bitcoin)

Bitcoin

The oldest cryptocurrency; on-chain confirmations are longer and fees fluctuate.

ETH (Ethereum)

ERC20 (Ethereum)

Native currency of the Ethereum chain; fees („gas“) are paid in ETH and can rise under load.

LTC (Litecoin)

Litecoin

Native currency of the Litecoin chain. A „lighter“ version of Bitcoin with faster blocks and low fees.

XRP (Ripple)

XRP Ledger

Native currency of the XRP Ledger. Fast, low-cost transactions, mandatory destination tag for correct deposit assignment.

USDC (USD Coin)

ERC20

Stablecoin pegged to USD, similar to USDT. Offered chains may vary.

BCH (Bitcoin Cash)

Bitcoin Cash

Native currency of the Bitcoin Cash chain. A Bitcoin fork with larger blocks. Low fees and faster confirmations than BTC.

DOGE (Dogecoin)

Dogecoin

Native currency of the Dogecoin chain. 1-min blocks, usually low fees, sometimes requires more confirmations.

ADA (Cardano)

Cardano

Native currency of the Cardano chain. Low fees, different address format.

SOL (Solana)

Solana

Native currency of the Solana chain. Very fast confirmation and low fees.

Security and cryptocurrencies

Crypto payments are fast but require precision. Follow a few simple rules to avoid most mistakes.

Wallet vs. exchange (where to store funds)

  • Smaller balances / quick deposits: keeping them on an exchange is fine for convenience.
  • Larger balances / long-term holding: belong in self-custody (your own wallet with a seed), ideally a hardware wallet.

Sending payments (most common mistakes)

  • The currency and chain must match (USDT-TRC20 ≠ USDT-ERC20).
  • For XRP/XLM, fill in the destination tag/memo—without it, the deposit won’t be assigned.
  • Copy the address; don’t type it manually. Check the first/last characters.
  • Start with a small test amount, then send the rest.
  • Verify the transaction status in a block explorer using the TX ID.

Account protection and sign-in

  • Enable 2FA (preferably app-based, not SMS).
  • Use strong, unique passwords and a password manager.
  • If the service offers an anti-phishing code or a withdrawal address whitelist, enable them.
  • Seed and backups (self-custody)
  • Never share or photograph your seed; keep an offline backup in a safe place.
  • Consider a hardware wallet for long-term storage.

Phishing and fake support

  • Download wallets only from official sources; bookmark website addresses.
  • Support will never ask for your seed/private keys.

Device and connection

  • Keep your OS and apps updated; avoid public Wi-Fi when sending payments.
  • Scan QR codes only from a trusted interface (the platform’s cashier).

Mini-checklist before sending

  • Do currency + chain match?
  • Is the address pasted correctly?
  • Do I need a tag/memo (XRP/XLM)?
  • Am I sending a small test amount first?
  • Did the test amount arrive where it should?
  • Is 2FA enabled?

Fees for crypto payments

To send tokens on most chains, you also need a small amount of the chain’s native coin to pay the fee (e.g., USDT-ERC20 → you need ETH, USDT-TRC20 → you need TRX, USDT-BEP20 → you need BNB). Without it, the transaction won’t go through.

Blockchain fees fluctuate with network load. The table below lists indicative on-chain fees for a typical transfer on the respective chain (not exchange/casino deposit/withdrawal fees). A given platform may add its fixed fee or spread to the final amount.

Chain

Typical on-chain fee

Bitcoin (BTC)

~€0.50–€1.35

Ethereum (ERC20)

~€0.30

BNB Smart Chain (BEP20)

~€0.02–€0.10

TRON (TRC20)

~€0.60–€1.60

Litecoin (LTC)

~€0.01

XRP Ledger (XRP)

~€0.001–€0.003

Bitcoin Cash (BCH)

~€0.01

Dogecoin (DOGE)

~€0.06–€0.07

Cardano (ADA)

~€0.10–€0.15

Solana (SOL)

~€0.0001–€0.003

Crypto deposit and withdrawal limits

Limits vary by brand for crypto and are most often tied to your account’s VIP level. In general, crypto limits tend to be higher than fiat, often even from the lowest level. You can always find specific values in the cashier or in our brand reviews.

How limits are typically set

  • By VIP level: higher levels increase daily/weekly/monthly caps for deposits and especially withdrawals.
  • By currency/chain: some brands have different minimums for USDT-TRC20 vs. USDT-ERC20, etc.
  • By transaction direction: withdrawals usually have tighter limits than deposits and sometimes waiting periods (manual checks).

KYC and where you send from

  • KYC is standard on gaming platforms.
  • Also important is the KYC status on the exchange/on-ramp you send from/to: an unverified exchange account may have low withdrawal limits regardless of the casino’s limits.

Method matching on withdrawal

  • Some brands require that withdrawals use the same method/currency as the deposit (AML rules). If you deposited USDT-TRC20, withdrawing USDT-TRC20 may be preferred.

What this means in practice

  • Crypto often has higher caps (already at the base VIP level), but specific numbers differ across platforms.
  • Check minimums and the chain directly in the cashier before sending.
  • Expect checks on withdrawals.
  • Check limits on the exchange you want to withdraw from/to.
Advantages
  • Fast crediting
  • Without „banking hours“ and weekends (24/7/365)
  • Often lower costs than international transfers
  • Stablecoins (USDT/USDC) hold value with USD
  • Higher limits than fiat (already from base VIP level)
  • Wide support across gaming platforms
  • Transparent tracking via block explorer
  • QR code = easy sending from mobile
  • Choice of chain (speed/cost)
  • Some brands offer special crypto bonuses

Disadvantages
  • More complex for newcomers (currency × chain)
  • Irreversible transactions (no chargebacks)
  • Volatility with non-stable coins
  • Different chain support across platforms
  • Risk of phishing / fraudulent addresses

Rating

Among payment methods, cryptocurrencies stand out for speed, 24/7 availability, and often higher limits than fiat. The initial barrier is handling chains and address formats. You must always choose the correct currency × chain and add a tag/memo for some currencies. After a few transactions, the process becomes routine. A small test, checking the first/last part of the address, and tracking the transaction status in a block explorer all help.

Stablecoins (USDT/USDC) reduce volatility, and choosing the chain (e.g., TRC20/BEP20 vs. ERC20) lets you balance cost and speed. The actual crediting time also depends on the platform (number of confirmations, internal checks); withdrawals may carry fixed fees and review delays.

For storing balances, a self-custody wallet makes sense if properly secured (seed offline, hardware wallet); otherwise, an exchange is more convenient. The biggest risks come from entry errors, since a transaction sent to the wrong chain/address is usually irreversible. With a disciplined approach, it’s a reliable payment method alongside payment cards and e-wallets.

Alternatives

Cryptocurrencies aren’t for everyone. Some users dislike the learning curve (currency × chain, tag/memo), fluctuating fees, or the fact that the user bears all responsibility. If you want similar speed and convenience without dealing with chains, e-wallets or mobile wallets linked to a card make sense. When choosing an alternative, focus on crediting speed, deposit/withdrawal limits, fees, and bonus eligibility.

Skrill is a fast e-wallet with broad support across gaming platforms and convenient mobile management. You pay without sharing card details with the casino, and the deposit is done in moments. Downsides include possible fees and, crucially, the fact that most casinos and sportsbooks exclude Skrill deposits from bonus eligibility.

Neteller works very similarly to Skrill. Fast deposits, multiple currencies, simple controls, and good availability. For everyday amounts, it’s a convenient choice with far less complexity than crypto. As with Skrill, Neteller deposits are often excluded from many bonuses, so keep that in mind.

Apple Pay and Google Pay provide the easiest way to pay by card in a few taps without retyping details. Speed is very good, but compared to crypto it’s a highly centralized solution (you depend on the bank/card issuer and service provider), and limits/refunds follow banking rules. For small to medium amounts, they offer an excellent balance of speed and convenience.

Revolut combines a fintech account and card: quick top-ups, virtual cards, fair FX rates, and a quality mobile app. Compared to crypto, it’s again a centralized service under banking regulation. For everyday small/medium payments, it’s a very practical alternative without blockchain complexity.

Glossary

Term

Brief explanation

Cryptocurrency

Digital currency running on a blockchain (e.g., BTC, ETH, USDT).

Blockchain / chain

A shared database that verifies and records transactions; each chain has its own rules, addresses, and fees.

Currency × chain

The currency is the token (e.g., USDT), the chain is the „payment route“ (TRC20, ERC20, BEP20). The same currency on a different chain ≠ compatible.

Address

The „account number“ on a chain (e.g., 0x… on ERC20, T… on TRC20, bc1… on Bitcoin). It’s specific to the chain.

Wallet

An app/device for holding and sending crypto. Can be custodial (managed by a service) or self-custody (you hold the keys).

Exchange (CEX)

Centralized exchange (e.g., buying crypto for EUR). Has its own limits, KYC, and withdrawal fees.

Self-custody

You hold the keys yourself (e.g., a hardware wallet). Maximum control and responsibility.

Seed (recovery phrase)

12–24 words to recover a wallet. Never store online or share with anyone.

Private key

Cryptographic key used to sign transactions. Keep it secret.

2FA

Two-factor authentication (app-based, not SMS). Protects your exchange/wallet account.

Address whitelist

A list of approved withdrawal addresses. Increases protection against theft.

Anti-phishing code

A short code in a service (often exchanges) that appears in support emails. Helps spot fake messages.

Memo / tag / destination tag

An additional identifier for some currencies (XRP, XLM). Without it, the deposit may not be assigned.

TX ID (hash)

A unique transaction identifier. Used to track in an explorer.

Block explorer

A website to check transactions and confirmations on a chain.

Confirmation(s)

The number of blocks that followed your transaction. Platforms require a certain count before crediting.

Fee / gas

A network fee paid to validators/miners. Varies by chain and load.

Spread

The difference between buy/sell rates during exchange; a hidden cost.

Stablecoin

A token pegged to fiat (e.g., USDT/USDC ≈ 1 USD). Reduces volatility.

On-ramp / off-ramp

Buying crypto with fiat / selling crypto back to fiat (SEPA, card, etc.).

Finality

The point at which a transaction is practically irreversible on a given chain. Finality speed varies.

Frequently asked questions

What if I sent to the wrong chain/address?
If the chain/address doesn’t match, the transaction is typically irreversible. Contact the casino and exchange support immediately; only in rare cases can it be located/refunded. For a missing tag/memo (XRP/XLM), contact support with the TX ID. Manual crediting is sometimes possible.
Do I need gas for every token?
Yes, on most chains you need a small amount of the native coin (ETH/TRX/BNB…) to pay the fee.
Why wasn’t my deposit credited right after the explorer shows confirmation?
The platform may require more confirmations or an internal check.
