This guide shows exactly how to fund and cash out with Bitcoin and Ethereum on licensed sportsbooks, what confirmations and fees to expect, when Lightning or Layer-2 can speed things up, and how to avoid common mistakes like sending on the wrong network. Bitcoin blocks arrive about every ten minutes on average, so services usually wait for at least one confirmation before crediting small deposits. Ethereum runs in fixed 12-second “slots” under proof-of-stake, with economic finality typically reached after a few minutes.
Before you start: legality, KYC, and player protections
Licensed online operators generally must verify your age and identity before allowing you to gamble. In Great Britain, the Gambling Commission requires remote operators to verify name, address, and date of birth, and it bars operators from delaying KYC until withdrawal if checks could have been done earlier. Operators must also disclose how customer funds are protected and display a rating such as not protected, medium, or high protection.

Bitcoin deposits: on-chain and Lightning
- Open the cashier and choose Bitcoin
Your sportsbook will display a BTC deposit address and may show different options for on-chain versus Lightning. Copy the exact address or Lightning invoice shown. - For on-chain BTC
Send from your wallet to the address provided. A new block is found roughly every ten minutes; many services credit after one or a few confirmations, while larger amounts may require more. On-chain payments are irreversible once confirmed, so test with a small amount first. - For Lightning
If supported by both your wallet and the sportsbook, pay the Lightning invoice for near-instant, low-fee crediting during live betting or when you need a quick top-up.
Tips
Use the exact network requested by the book, check the address checksum, and consider paying a competitive fee during congestion to avoid slow confirmations.
Bitcoin withdrawals
- Enter your own BTC address or Lightning invoice
Double-check you pasted the right destination. - Confirm processing and fees
Books often batch on-chain withdrawals or offer Lightning for faster, cheaper payouts when available. On-chain finality still depends on block confirmations. - Secure storage
Move larger balances to self-custody you control, and enable app-based 2FA anywhere possible.
Ethereum deposits: mainnet and Layer-2
- Open the cashier and choose Ethereum
Confirm which chain the sportsbook supports. Some sites accept only Ethereum mainnet; others also support Layer-2 networks like Optimistic or ZK rollups. - For mainnet ETH
Send ETH to the address the book shows. Ethereum uses a base fee plus a small priority tip (EIP-1559). Fees vary with demand; at busy times you’ll pay more. - For Layer-2 (if your book supports it)
Layer-2s process transactions off-chain and post data to Ethereum, typically charging much lower fees than mainnet—often cents—while confirming quickly from a user’s perspective. Select the exact L2 network the cashier lists.
Timing notes
Time in proof-of-stake Ethereum is divided into 12-second slots. Blocks are proposed each slot, and protocol finality arrives after validators finalize checkpoints over epochs, generally within minutes.
Ethereum withdrawals
- Paste your receiving address on the same network you deposited from
If the book pays on an L2, make sure your wallet supports that L2; if it pays on mainnet, use a mainnet address. - Review fees and settlement
Your withdraw tx will use EIP-1559’s base fee plus tip on mainnet or the L2’s fee schedule. Expect faster user-level settlement on L2s. - Move funds to safer storage
For balances you’re not actively betting, use self-custody and back up your recovery phrase offline.
Fees and speed at a glance
Bitcoin on-chain
Average block interval is about 10 minutes, and the network retargets difficulty every 2016 blocks to maintain that rate. Fees fluctuate with demand.
Bitcoin Lightning
Payments route through payment channels anchored to Bitcoin, enabling near-instant, low-fee transfers when supported by both sides.
Ethereum mainnet
EIP-1559 adjusts a burned base fee each block based on demand; you may add a small tip for priority.
Ethereum Layer-2
Optimistic and ZK rollups reduce per-transaction costs and improve throughput while ultimately inheriting Ethereum’s security. Many users see cents-level fees.
Common mistakes to avoid
Sending on the wrong network
Never send an L2 or alternative-chain asset to a mainnet-only address, or vice versa. Always match the network indicated in the cashier.
Skipping KYC until withdrawal
Regulated operators cannot demand identity checks only at withdrawal if they could have asked earlier. Complete verification upfront to prevent payout delays.
Assuming crypto payments are reversible
Once confirmed, you cannot “charge back” a blockchain payment the way you might with a card. Verify addresses and amounts before sending.
Security checklist for crypto sportsbook payments
Enable two-factor authentication on sportsbooks and exchanges, store recovery phrases offline, start with a small test transaction, and avoid leaving large balances in hot custodial wallets between events. For UK-licensed sites, review the operator’s published customer-funds protection rating and withdrawal terms.
Frequently asked questions
How many Bitcoin confirmations do I need?
Policies vary by site and amount, but you’ll commonly see crediting after one or a few confirmations. Bitcoin’s average block interval is about 10 minutes.
Is Lightning really faster for deposits?
Yes. Lightning uses off-chain payment channels to enable near-instant, low-fee transfers when both your wallet and the sportsbook support it.
Why were my Ethereum fees high?
Mainnet fees are set by EIP-1559’s base fee plus a small tip and rise during congestion. If your book supports Layer-2, you’ll typically pay much less.
Will the sportsbook make me complete KYC to withdraw?
Licensed operators must verify identity before allowing gambling and cannot wait to request verification only at cash out if it could have been done earlier.
Where can I get help for gambling problems?
In the United States, call or text 1-800-GAMBLER for the National Problem Gambling Helpline.
