XSeed - Backup Your Private Keys

A private key is a crucial part of crypto trading. It is similar to a password. It is used to sign transactions and act as proof of the ownership of a blockchain address. It is a secret number, a collection of randomly generated alphanumerical characters. 

Your crypto wallet has public and private keys. While anyone can use the public key/ address to deposit money, the private key is necessary to withdraw money from the crypto wallet. The private key is also stored in offline or physical wallets by creating a partition. Or, you can use smartcards or backup cards to securely store the information. The backup cards can hold private keys for multiple blockchain addresses. 

SecuX Technology is a famous company known for manufacturing some of the best hardware wallets in the market. The same company is also offering tamperproof, waterproof, and fireproof backup cards to save private keys.

How to Store Crypto Private Keys 

In simple terms, anyone who owns cryptocurrency actually owns private keys. And when others gain access to the private keys, they have access to your crypto funds. How well you protect the private keys determines how safe your cryptocurrency is. That’s why many people prefer hardware wallets or physical wallets and backup cards to store cryptocurrencies. 

Digital wallets are also safe, and even the vendor cannot access your funds or private keys. However, it is connected to the internet. This gives hackers a higher chance to break into the software and steal your cryptocurrency. Cyber crypto theft is not uncommon. 

When you use hardware wallets and backup cards, no one else but you have access to them. Moreover, thieves cannot decrypt the passwords or private keys when stored in physical devices.
