What is paper wallet?

[Yugocean]

In the cryptoworld, a "paper wallet" is literally the wallet's vital information printed on a piece of paper, either directly or in the form of a QR code.

Pros ​	Limitations​	Cons​
It is a cold wallet that works without the internet. This leaves no way for hackers to access your cryptocurrency.​	Only one currency can be stored in a paper wallet. Storing more than one cryptocurrency would require multiple wallets.​	Printing Ink on paper doesn't last forever, so if even a part of it gets erased, you'll lose all access.​
This is the cheapest hardware wallet. You only have to bear the one-time paper and printing cost. Nobody will care if you have some paper with you​	The wallet has to be swiped every time you want to complete transaction, this can be problematic.​	Paper is fragile, so if you lose it or it tears, your access to your stored crypto is lost forever.​

Several years ago I tried to use a crypto paper wallet, which is included in the cold wallet category because it is not connected to the internet. Very safe if used to store crypto in the long term. To be able to use a paper wallet the first time we have to create a "public key" and a "private key". The public key is used to receive crypto, while the private key is used to access the wallet. As the name suggests, it is a paper wallet, so we can print it on paper. Unfortunately, to withdraw, we have to import the private key to a crypto wallet that supports it.
