help Bitcoin FAQ
Why do people say Bitcoin started with the genesis block in 2009?
Bitcoin's first block, known as the genesis block, was mined in January 2009 after Satoshi Nakamoto published the white paper in 2008. That makes it the first widely adopted cryptocurrency network using proof-of-work and a public blockchain.
What does Bitcoin's 21 million supply limit actually mean?
Bitcoin's protocol caps issuance at 21 million coins, with new coins released to miners through block rewards. Those rewards are cut roughly every 210,000 blocks, an event commonly called the halving.
Can Bitcoin transactions be reversed like a credit card chargeback?
No, confirmed Bitcoin transactions are not reversed by a bank or payment processor. If coins are sent to the wrong address, recovery depends on the recipient voluntarily sending them back.
Why is Bitcoin often compared with Ethereum even though they do different things?
Bitcoin is mainly designed around decentralized money and settlement, while Ethereum added a broader smart-contract platform after launching in 2015. The comparison is common because both are major public blockchains, but their design goals are different.
