Bitcoin is a decentralized electronic cash system that uses a peer-to-peer network to prevent double-spending.
Users hold the crypto keys to their own money and transact directly with each other, with the help of a P2P network to check for double-spending.
Bitcoins can be sent easily through the Internet, without having to trust middlemen and transactions are designed to be computationally prohibitive to reverse.
Bitcoin Portable helps you stay safe from instability caused by fractional reserve banking and central banks. The limited inflation of the Bitcoin system’s money supply is distributed evenly (by CPU power) throughout the network, not monopolized by banks.
