Anyone reading up on "bitcoin wallet app" needs one idea first: an address is public, a key is not. A wallet address is the public string a wallet shows for receiving coins. Anyone who knows it can send to it, but only the matching private key can move what arrives. On public networks an address still reveals the balance and history behind it. For a player moving coins to and from a casino, reading an address correctly matters as much as reading the sum.
To track a bitcoin transaction, copy its transaction ID, also called the hash, from the wallet's history and paste it into a bitcoin explorer. The result shows whether the transfer is still waiting or already confirmed, how many confirmations it has gathered and what fee was paid. Confirmation time depends on how busy the network is and on the fee offered, so a low fee can leave a transfer waiting for a long while. Searching an address instead shows its balance and every transfer, open to anyone who has it.
A bitcoin wallet address is a long run of letters and digits that usually starts with 1, 3 or bc1, depending on its type. Finding the address of a personal wallet means opening it and tapping Receive. Many wallets show a fresh bitcoin wallet address for each payment to protect privacy, and older ones keep working. The receive screen also shows a square code the camera can scan, which avoids typing errors. A pasted address still deserves a second look, with characters at its start, middle and end compared against the original.
