How To Store Bitcoins?
Bitcoin is a cryptocurrency, so it does not have a physical form. In order to store his or her coins, a BTC holder uses a special wallet that contains a pair of keys — a public and a private key. The pairs are generated from a unique 12-word code phrase (seed) that every user has. If you have access to this phrase, you have access to your funds. You should never show your seed-phrase to anyone.

Public and private keys work in pairs. The public key is used as a wallet address, and the user receives money to it. The private key must be kept in secret.
A user can have several different wallets for different purposes. For example, to store cryptocurrency or to pay for purchases. There are different types of wallets with different levels of security.

A hardware wallet case can be made of different materials. A titanium case is much more durable than a plastic one. Other brands offer waterproofness, etc.
Own operating system
This is a very important factor of protection. It is much more difficult to create malicious software to bring harm to a unique OS rather than to a well-known one, like Windows or Android. A good example is OS Ledger.

A paper wallet is considered the most reliable cryptocurrency wallet type. In the simplest form, this is a sheet of paper that contains an image of the code phrase itself in an explicit or encrypted form (for example, a QR code that can be read by a scanner or a mobile device). Of course, you do not necessarily have to use paper, as durable materials are more preferable. The main thing here is to ensure the safety of the wallet and not to lose access to it.
- A printer used to create a paper wallet can be connected to other devices.
- It can get damaged, lost, destroyed, or stolen.
A paper wallet is a type of "cold" storage, because it is used without the Internet connection. In order to ensure its safety, users store it in a secure place, such as a home safe or a safe deposit box.
