How to buy bitcoin

Whoever asks "How to buy bitcoin?" 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.

A blockchain explorer is a public website that reads a network's records and presents them in plain form: transfers, addresses, balances, fees and confirmations. Each network has its own, so a TRC20 transfer is looked up on a TRON explorer and a bitcoin transfer on a bitcoin one. Using a blockchain explorer needs no account, only a hash or address pasted into its search box. A screenshot proves nothing when the hash cannot be found there, while transfers inside one exchange may never reach the network and appear only in its own history.

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 checked against the original.
