As such, a Bitcoin wallet is like a key to your safe deposit box on the Blockchain. Private keys emerged as a way to communicate securely through insecure communication channels. As a solution, the use of two keys public and private entered the picture.
Keys come in pairs. The public key is used to encrypt the message whereas the private key decrypts the message. The only person with the private key is you. Everyone else is free to have your public key. As a result, everyone can send you encrypted messages without having to agree on a key beforehand. They simply use your public key and you untangle the gibberish by using your private key.
At the end of the day, all of this can go over your head without much danger. Bitcoin wallets make use of a fundamental cryptographic principle that we use for things ranging from https for websites or sending anonymous tips to Wikileaks.
A Bitcoin address is like an account number, just better. The address denotes which wallet the coins should be sent to. Like a bank account number, where the difference lies in the wallets having multiple addresses.
These can be customized by including payment request information such as an amount and a date of expiration. Bitcoin wallet addresses are case sensitive, usually have 34 characters of numbers and lowercase letters, start with either a 1 or a 3, and never use 0, O, l and I to make every character in the address as clear as possible. What they consist of is largely irrelevant to you. How to generate a new Bitcoin Address varies between wallets.
Some manage your addresses for you. Others give you full control. As with many other Bitcoin technologies, the option to dirty your own hands is always open. If you do end up taking the easier route, just press a button to generate a new address for your wallet.

After all, we need to be connected to the internet to send value from one wallet to another over the Blockchain.
To some readers this might seem like a weird question. Truth is, people coming from a financial or business background are likely to expect Bitcoin to be a direct alternative to our current financial system.

By following a few pointers below, you can set one up entirely for free. Of course, this means that keeping a record of them is even more important. To keep it very simple, paper wallets are an offline cold storage method of saving cryptocurrency. It includes printing out your public and private keys on a piece of paper which you then store and save in a secure place.
The keys are printed in the form of QR codes which you can scan in the future for all your transactions. The reason why it is so safe is that it gives complete control to you, the user. You do not need to worry about the well-being of a piece of hardware, nor do you have to worry about hackers or any piece of malware. You just need to take care of a piece of paper.
The answer to this question will largely depend on your circumstances. Paper wallets are formed by using a program to randomly generate a public and private key. The keys will be unique, and the program that generates them is open source. Those with advanced knowledge of coding can check the backend of the program themselves for randomicity in results. This eradicates the exposure to online threats, and deleting the simple program after use will destroy any trace of them.

A safe is usually favored for this. Only those allowed access to the funds must know the combination and preferably existence of your security box.
If you have sole access to a high-quality safe, you should use this, otherwise risking a lower end model may be your best option. Either way, only those who have ownership of the coins stored on the paper wallet must know the combination to the lock.
