In one sentence: bitcoin is digital money that moves between people without a bank in the middle, with a supply capped at 21 million coins.
In one paragraph: the record of who owns what is a public ledger copied across thousands of computers. New transactions are grouped into blocks roughly every ten minutes by miners, who compete to secure the network and are paid in newly issued bitcoin plus fees. No company runs it and nobody can issue more than the rules allow. Open ledger, fixed issuance, no central operator - that is the whole design. Everything else people argue about is built on top of it.
