A Bitcoin wallet allows someone to send and receive bitcoin.
The wallet does not store physical coins, rather it holds data about transactions to and from that wallet.
Bitcoin wallets use cryptography to ensure high network security when bitcoin is being sent to or from a wallet.
The most important part of a wallet is the private keys. Whoever has access to the private keys can access the coins from the wallet, and send them to another wallet address. So it is very important that you take care of your private keys and do not share them with anyone else.
Theoretically, there is no limit to how much bitcoin can be held in a single wallet.
In total there will only ever be 21 million bitcoin. To date, about 19 million have been mined. It is thought that around 3 million of those bitcoin mined to date may have already been lost.
