From beginner to advanced — master exchanges, wallets and blockchain essentials
An unverified bitcoin transaction usually means a transfer has been broadcast but not yet confirmed in a block. The key is status, fees, and double-spend risk.
Why do bitcoins need to be mined? Mining lets an open network pick who updates the ledger and rewards those who keep Bitcoin secure.
How does bitcoin security work? It relies on private keys, node verification, and proof of work to protect ownership and block history.
Bitcoins have to be mined because mining confirms transactions, orders the ledger, secures the network, and releases new BTC by rule.
Why was Bitcoin created? It was built to enable peer-to-peer electronic cash without relying entirely on a central institution to keep the ledger.

Bitcoin is not made of metal or paper. It consists of code, blockchain records, cryptography, and network consensus.
