From beginner to advanced — master exchanges, wallets and blockchain essentials
Bitcoin dates back to 2009 if you count the live network, or 2008 if you count the white paper. The answer depends on where you start the clock.
Why is Bitcoin worth money? Its value comes from scarce supply, verifiable ownership, transferability, and market consensus around open rules.
Bitcoin has a hard cap of 21 million coins, but the amount people can actually use is lower because supply is released over time and some coins are lost.
A bitcoin miner works by joining a record-keeping race: it hashes block data again and again to help validate transactions and secure the network.
There is no single answer to “how many bitcoins sold.” First separate trading volume, circulating supply, and your own sale records.
How many bitcoins are yet to be mined depends on the 21 million cap and the halving cycle. Here’s how issuance, mining, and costs really work.
How many bitcoin remain to be mined? Bitcoin has a fixed cap of 21 million, and the remaining supply shrinks over time as block rewards keep falling.
How many more bitcoin can be mined? Bitcoin has a 21 million cap, and the remaining supply will be released more slowly over time.
