A wallet of any cryptocurrency can store multiple public and private keys. The cryptocurrency is itself not contained in the wallet; instead, the cryptocurrency is de-centrally stored and maintained in the public ledger. Every cryptocurrency has a private key with which it is possible to write in the public ledger, which makes spending in the cryptocurrency possible.
It is important to know about the wallets, since keeping the private key secure is crucial in order to keep the currency safe. Wallet is a collection of public and private keys, and each of them is important for the security and anonymity of the currency holder.
