The majority of digital funds are stored in an offline cold wallet which hackers cannot access. This is different to an online hot wallet that is more vulnerable to hacking attacks. The main difference is a hot wallet remains connected to the Internet and a cold Bitcoin wallet is kept offline.
Thus, your digital funds are more accessible in a hot wallet but staying online makes the private keys stored in your wallet vulnerable to cyber theft.
The functions needed to complete a fund transaction are made from a single online device and the hot wallet generates and stores private keys. Individual transactions are broadcast online across the blockchain network. You can keep a limited amount of Bitcoin in a hot wallet and leave the rest stored safely in a cold wallet. A cold wallet is also referred to as cold storage.
When you initiate a fund transaction, it is temporarily transferred to an offline wallet device such as a USB, computer disc, hard drive or even a paper copy. A hacker cannot intercept a fund transaction because the private key never comes into contact with a server connected online. The only risk is if the wallet is lost, stolen or damaged. A way to get around lost, damaged or destroyed hardware wallets is to make a reliable back-up copy or clone of it. Private keys in a hot wallet can also go missing if the Bitcoin exchange facility has a software glitch or its system is corrupted.
Most serious Bitcoin investors use a combination of hot and cold wallets. Some of their digital funds are loaded onto a hot wallet which can be accessed instantaneously and the bulk is loaded onto a cold wallet which is the most secure way to store Bitcoins. This is a paper document with your private keys recorded on it.
The paper wallet usually has a QR code embedded in it so it can easily be scanned and signed to make a transaction. A hardware wallet uses a mobile device that is specially designed to hold private and public keys.

It looks like a USB flash stick which you insert into your computer or mobile device, You connect to the Internet when you want to do a transaction. A hardware wallet comes with a desktop app which stores the private keys offline. A desktop wallet is software downloaded on your PC or laptop and hosted in the cloud.
Cloud-based wallets are more user-friendly and convenient but it means a third-party has control of your private keys. Software systems are susceptible to cyber hacking and theft. Mobile wallets are available as apps for Smartphones. They are useful if you want to use your Bitcoin to buy products online.
Most Bitcoin wallets are designed to be mobile-friendly. Software wallets are similar to hardware wallets but are a lot more complex. Basically, an offline software wallet splits a wallet into two accessible platforms; one contains the private keys and one contains the public keys. A Bitcoin address identifies the source or destination of a Bitcoin payment. To give instructions to buy or sell Bitcoin , the wallet software automatically generates a unique Bitcoin address for you.
At the same time, you are allocated a unique password known as a private key. This is so hackers can never get their hands on your private key. Bitcoin is built on cryptology which is a system of encryption that uses a combination of public keys and private keys to access the blockchain. Public keys are identifiable; they are known to the public and are used to identify the user. Private keys are secret numbers that only you know and are used for authentication and encryption.
A private key is the first thing that is generated for a Bitcoin address and the public key is derived from the private key using a known algorithm.
The Bitcoin wallet address you use for digital currency transactions is a shorter version of the public key. The public key is required to receive Bitcoins. A Bitcoin wallet address is a hashed version of your public key. Without getting too technical; every secret key is bits long and the final hash — wallet address — is bits long. The private key is required to spend Bitcoin.
When you send Bitcoin from a Bitcoin wallet, the software links the transaction to a private key but without disclosing what it is. This provides proof to the blockchain network that you have the authority to transfer the digital funds from the address you are using. Your Bitcoin wallet will have one or more private keys which are saved in a wallet file. You never personally handle a private key; instead you are given a seed phrase that encodes the same information as the private key.
A seed phrase is short for seed recovery phrase or backup seed phrase.
Wallet software prompts you to write down the seed phrase on paper and file it somewhere safe. If and when you need to recover your Bitcoin wallet, you download the same wallet software and use the seed phrase to get your Bitcoins back. If someone gets their hands on your seed phrase, they can steal your Bitcoins. So be careful; treat your seed phrase like you would expensive jewelry and keep it locked in a safe.

Think of the private key as being the credit card and the password is the PIN number. Keep your password secret and written down and kept in a safe place. Two-factor authentication means simply setting up your Bitcoin wallet to check two forms of identity instead of one. There are 3 ways to authenticate yourself with 2FA;.

The transaction fee covers miner fees, storage and the cost of the service. The fee rate is dynamic because it all depends on blockchain congestion. The faster you need the transaction to happen, the higher the fee will be. A small administrative fee is charged by the Bitcoin exchange facility to withdraw and deposit local currency into a wallet. Check the latest fees on the website.
There are different Bitcoin wallets and different degrees of safety. It all depends on what type of Bitcoin wallet you use and the service provider. You have a choice of desktop, mobile, online, paper, hardware or software wallets. A Bitcoin wallet that is linked to the Internet is regarded as less safe because of the risk of a cyber attack by hackers. These wallets are called hot wallets and may be any device that stays connected to the Internet.
Offline wallets or cold wallets as they are called are not connected to the Internet and therefore not vulnerable to being hacked. The most important thing to remember is if you lose, damage or destroy your private keys; you will lose your digital funds.
