A wallet is a program for receiving, sending and storing bitcoins or other cryptocurrencies. Wallets connect to the blockchain, the accounting book that stores the transactions and balances of a crypto-currency. There are, however, several types of wallets.

The wallets store the private keys – encrypted codes used to generate the public keys and the address where your bitcoins are stored.

A default wallet creates a text file that contains your private key. If someone discovers this key, they can have control over your bitcoins. So it is important to store it securely on an encrypted disk or computer. It is worth even copying it in a paper and hiding it.


Acronym for hierarchical deterministic. They are basically wallets that generate an initial phrase called seed or mnemonic phrase. These are usually words in English that are easier to write than a private key, for example. If the wallet is stolen, for example, just use the word combination to gain access to it again. Therefore words must be kept in absolute secrecy and safety.
