Step by Step
On the betting site, open Deposit → Bitcoin and copy the address (or scan the QR). On your exchange or wallet, choose Send/Withdraw, paste the address, select the Bitcoin network, and start with a small test amount. Verify the first and last characters of the pasted address match — clipboard malware that swaps addresses is real. Confirm and wait: books credit after 1-3 confirmations, roughly 10-30 minutes.
The Three Costly Mistakes
Wrong network is the big one: sending BTC over any network the receiving address doesn't support (e.g. picking BEP-20 'BTCB' when the site expects mainnet) can lose funds permanently. Second: sending below the site's minimum, which may not credit. Third: reusing an old deposit address after a site rotates addresses — always fetch fresh.
Fees and Timing
Bitcoin network fees float with congestion — a few cents to several dollars. Exchanges add their own withdrawal fee (often ~0.0002-0.0005 BTC). If fees annoy you, this is exactly why most bettors switch to Litecoin or TRC-20 USDT for transfers: same workflow, fees under $1, faster confirmations.
