For long-term holders, here are some methods to secure your assets:
First is the hardware wallet. This is a relatively secure method, similar to a USB drive that stores the private keys. Brands like Trezor and Ledger offer hardware wallets, which do not expose the private keys to the network during use, reducing the risk of being hacked. Additionally, hardware wallets typically have a PIN code to enhance security; even if the device is lost, it is difficult for others to access the assets without the PIN.
Next is the paper wallet. It is a cold storage method that prints the public and private keys on paper. You can create a paper wallet using some wallet generation tools. But be careful to keep the paper secure after printing to avoid moisture, damage, or unauthorized access to the information.
You can also use encrypted software wallets. Software wallets have various encryption methods to protect assets. For example, choose wallets that support multi-signature, which require multiple key authorizations for transactions, increasing the security of asset transfers. However, be sure to download software wallets from official channels to prevent downloading tampered versions, and regularly update the software to ensure security.
Additionally, decentralized storage is very important. Do not keep all your coins in one wallet; you can distribute your assets across different types of wallets (such as hardware wallets and software wallets) or different storage locations. This reduces the risk of losing all assets if a single wallet encounters issues. Also, make sure to back up your wallets properly, such as securely backing up the recovery seed phrase for hardware wallets and storing it in a safe place, like a safe.
