Web Wallet refers to a wallet that stores virtual currency on the Internet.
Since the wallet is on a web service, it has the advantage of being accessible from anywhere. However, as long as it is connected to the Internet, there is always the risk of being hacked.
The security aspect is managed collectively by the institution providing the service, so it is important to choose a site that you can trust.
It is not recommended for managing a large amount of bitcoins, as the site may be hacked by a third party.
Other types of wallets include desktop wallets (wallets on PCs), mobile wallets (wallets on smartphones), paper wallets (printed on paper), and hardware wallets (dedicated devices).
Offline wallets, which are not connected to the Internet, and decentralized management allow you to safely store your cryptocurrency.
