Cryptocurrency should be stored in a special wallet. The wallets differ in the type, security, convenience of access and use. We will inform you about everything that you need to select a purse.
What is bitcoin wallet?
This is a special program that generates address and control keys, and then may generate requests for transactions, to sign their key and send the attestation to the network. If someone were to gain access to the keys, it will clean out the purse so the security of key storage is the main criterion.
The purses are divided into types depending on exactly where keys are stored and how queries get signature private keys. There are 3 types:
- Soft-wallets — program on the computer or on the phone, the keys are encrypted;
- Online wallets — in a web browser, an analogue of online banking, keys are stored on the server.
- Hard-purses — keys are stored in a special storage, access to which is password protected.
The choice of the purse depends on how often you use the wallet and what transactions are carried out. For example, there is no reason to buy hard wallet for $100 to keep $10 in Bitcoins.
