Cryptocurrencies by their nature are an electronic means of payment. Coins appear as a result of mining, are stored electronically, and all operations take place on the Internet. Nevertheless, bitcoin can be put into a regular wallet. Let's figure it out
And so, everyone has heard the comparison of bitcoin with gold and precious metals. In fact, this parallel is much deeper than one might imagine. You can really put Bitcoin in your wallet and keep your coins closer to your heart, and this will not be too far from the truth.
As we said in our article COLD STORAGE - “COLD STORAGE” BY THE EXAMPLE OF BITCOIN, the basis of the Bitcoin wallet (and most well-known cryptocurrencies) is the pair public key/private key(public key/private key). A further development of the same idea that is used for Cold Storage is the ability to store private keys on almost any medium, because the volume of a private key in the WIF format does not exceed several hundred bytes. For example, for the address

the private key in WIF format will look like this:

Several of these lines will easily fit in notes on a smartphone, on the smallest flash drive or on an SD card. Agree - putting modern flash drives or micro-SD cards into a wallet is not a problem. However, you can go much further.
An example of a bitcoin address and a WIF wallet in the form of a QR code
This is what a bitcoin address and the key to it look like in the form of a QR code - a special format for reading by any smartphone. You can print a QR code with an address in any quantity and distribute it to everyone who wants to share coins with you, and store the printout of the WIF wallet in a secluded pocket of your wallet, although it is better, of course, to store the key in a safe, away from prying eyes.
