Definition of ‘Bitcoin Wallet’
A Bitcoin wallet is a software program where Bitcoins are stored. To be technically accurate, Bitcoins are not stored anywhere; there is a private key (secret number) for every Bitcoin address that is saved in the Bitcoin wallet of the person who owns the balance. Bitcoin wallets facilitate sending and receiving Bitcoins and gives ownership of the Bitcoin balance to the user. The Bitcoin wallet comes in many forms; desktop, mobile, web and hardware are the four main types of wallets.
Investopedia explains ‘Bitcoin Wallet’
A Bitcoin wallet is also referred to as a digital Wallet. Establishing such a wallet is an important step in the process of obtaining Bitcoins. Just as Bitcoins are the digital equivalent of cash, a Bitcoin wallet is analogous to a physical wallet. But instead of storing Bitcoins literally, what is stored is a lot of relevant information like the secure private key used to access Bitcoin addresses and carry out transactions. The four main types of wallet are desktop, mobile, web and hardware.
Desktop wallets are installed on a desktop computer and provide the user with complete control over the wallet. Desktop wallets enable the user to create a Bitcoin address for sending and receiving the Bitcoins. They also allow the user to store a private key. A few known desktop wallets are Bitcoin Core, MultiBit, Armory, Hive OS X, Electrum, etc.
Mobile wallets overcome the handicap of desktop wallets, as the latter are fixed in one place. Once you run the app on your smartphone, the wallet can carry out the same functions as a desktop wallet, and help you pay directly from your mobile from anywhere. Thus a mobile wallet facilitates in making payments in physical stores by using “touch-to-pay” via NFC scanning a QR code. Bitcoin Wallet, Hive Android and Mycelium Bitcoin Wallet are few of the mobile wallets.
As for web wallets, they allow you to use Bitcoins from anywhere, on any browser or mobile. The selection of your web wallet must be done carefully since it stores your private keys online. Coinbase and Blockchain are popular web wallet providers.
The number of hardware wallets is currently very limited. These devices can hold private keys electronically and facilitate payments but are still in the development phase.
Keeping your Bitcoin wallet safe is very crucial. Some safeguards include: encrypting the wallet with a strong password, and choosing the cold storage option i.e. storing it offline.
