Bitcoin is a digital currency, a protocol, and a software that enables instant peer to peer transactions, worldwide payments and much more.
A Bitcoin wallet refers to the equivalent of a physical wallet on the Bitcoin network. Each Bitcoin wallet can show you the total balance of all Bitcoin addresses it contains. Just like you can count the money in your real wallet.
