What Are Bitcoin Wallets?

[nuroxx02]

Storing bitcoin in a safe location has its challenges. This is because bitcoins aren’t physically “stored” anywhere. As a purely digital entity, it is not as if they are held in bank vaults or stuffed under mattresses. They are accessible through Bitcoin addresses, which require a set of digital keys for entry. So, the question of how to securely store bitcoin comes down to the security of these keys.

Bitcoin wallet on computer
You must download the application. Keys are stored locally (if HD wallet technology is not used). Such wallets are:
thick - you need to download the entire chain of blocks and download new ones (the most reliable option);
thin - you don’t need to download full chains, so it’s convenient to use on smartphones and tablets, but one hundred percent security is not guaranteed.
Online Bitcoin Wallets
It is not necessary to download absolutely all network blocks, that is, save time and device memory. You can manage it remotely (via the Internet), save the addresses of other wallets, transfer bitcoins. Notifications are often provided.
There is a risk of service hacking and theft of virtual money. Experienced users recommend storing small amounts for a short time.
Mobile Wallets
They give access to bitcoins using devices based on iOS and Android. The technologies of reading and recognizing QR codes or NFC (Near Field Communication) are used.
Bitcoin Wallet is a standalone wallet for Android. The balance is displayed in different formats and currencies. Addresses are saved. Allows you to pay via Bluetooth, sends notifications about the receipt of bitcoins.

With all the wealth of choice, for storing crypto, in my opinion, it is better to use a cold blockchain wallet (convenient, reliable, since 2012 in the industry, the coma has calmed down and is now small - about the average daily average of 0.00009246 BTC) or hardware multi-currency wallets - Ledger Nano S or Trezor.

That is why the Bitcoin community always recommends using hard wallet to store Bitcoin. Hardware wallet are also known as cold storage as they are not connected to the internet 24/7. The also store their private keys within themselves. You only need to keep a backup of it.
