A “wallet” is basically the Bitcoin equivalent of a bank account. It allows you to receive bitcoins, store them, and then send them to others. There are two main types of wallets. A hot wallet is one that you install on your own computer or mobile device. You are in complete control over the security of your coins, but since they are on a device that is connected to the internet they are less secure. The second type of wallet is a hardware wallet. They maintain high levels of security to protect your coins by storing your coins offline. Offline storage keeps your coins and ata out of reach from hackers.

It seems that nearly every day there’s another report of a major hacking. And as the number of hacks increase, consumer desires for security increase as well. Blockchain is the model of internet security, that doesn’t produce a fully secure system for users. There are a number of important safety and security practices that can help to protect your private keys and therefore protect your funds.
first it is wise to find a wallet with security measures beyond the normal wallet providers. Some wallets are now using encryption to protect the private keys. Users should always have at least two digital wallets. One wallet should be used for trading and transactional purposes, and the other wallet should be used to store savings and be kept in a secure location. This type of wallet must be a cold storage wallet. In anyway, a backup of the private keys have to be stored safely offline. This two safety tips can help you to avoid hacking your wallet.
