Cryptocurrency gives users full control of their money, but this freedom also comes with responsibility. In contrast to traditional banking systems, there is typically no customer support team available to help you recover your funds if your wallet is hacked or your private keys are stolen. Hence, most crypto investors resort to offline storage or cold storage to keep their digital assets safe.
One of the safest ways to store cryptocurrency is offline storage, as it disconnects your private keys from the internet. An offline wallet is far more difficult to access remotely by hackers, so the threat of phishing, malware or exchange breaches is much less. Cold storage is generally preferable for long-term investors or those with large balances.
Offline crypto storage is the storing of your wallet’s private keys on a device/medium that is not always connected to the internet. The most important part of any crypto wallet is the private keys, as they are the key to accessing your funds. Anyone who gets these keys can move your crypto without your permission.
Hot Wallets (Exchange Wallets or Mobile Apps) are always on the internet for convenience. They're easier to use in day-to-day trading, but are also more vulnerable to cyberattacks. Cold wallets reduce this risk by keeping sensitive information offline.
The most common forms of offline storage are:
- Wallets based on hardware
- Paper wallets
- Seed phrase backups offline
Hardware wallets are one of them and are the safest and most practical solution for most of the crypto users.
Hardware Wallets
Hardware wallets are tangible devices built for the safe storage of crypto. They keep their private keys offline, away from internet-connected machines, and sign transactions offline. Even if your computer is infected with malware, the keys in the hardware wallet are secure.
Easy to use and supports many cryptocurrencies, popular hardware wallets. They strike a good balance between convenience and security and are perfect for long-term storage.
Always purchase a hardware wallet directly from the official manufacturer or an authorised seller. Never buy second-hand devices, they could be compromised.
Paper Wallets
A paper wallet is just a printout of your public and private keys, often represented in QR codes. It cannot be hacked remotely because it is completely offline.
Paper wallets also carry a risk. Paper is easily damaged by water, fire or fading ink. It could also be lost or stolen. These weaknesses make paper wallets less popular than hardware wallets nowadays.
Seed Phrase Storage
Every crypto wallet produces a recovery phrase, also known as a seed phrase. Typically, it's a list of 12 or 24 words that can get you back into your funds if the wallet is lost or broken.
The seed phrase is just as important to protect as the wallet itself. Experts recommend that you write the phrase down by hand and store it offline in a secure place such as:
- A fireproof safe.
- A safe locker
- Fire and water-resistant metal backing plate
Never store your recovery phrase in your email drafts, cloud storage, screenshots or notes on your phone.
First, you’ll want to pick a trustworthy hardware wallet from a reputable company. Once you receive the device, set it up in a private and secure location.
Your wallet will generate a recovery phrase when you set it up. Write it down carefully and check each word in the right order. This phrase is your funds only backup.
After setting it up, send a small amount of crypto first to make sure the wallet is working properly. Always double-check the wallet address on the hardware wallet screen before sending funds. In some cases, scammers will use malware to replace copied wallet addresses with fake addresses.
Once this is confirmed you can start moving larger amounts into cold storage.
Keep Your Wallet and Recovery Phrase Separate
Never house the hardware wallet and seed phrase in the same location. If both are stolen in one incident, your crypto can be compromised.
Many users keep one backup at home and another at a different, secure location.
Never Give Out Your Seed Phrase
No real company or support agent will ask you for your recovery phrase. If anyone asks for it they are almost certainly trying to steal your money.
Treat your seed phrase like the master password to your money life.
Update Your Software
Offline wallets are very secure, but you should still update the wallet’s firmware from official sources on a regular basis. Security updates protect against newly discovered security flaws.
Storing the recovery phrase on a digital device is a big mistake. Screenshots, USB drives, cloud backups and email storage may seem convenient but they also add another security risk if hacked.
Another mistake is to not test wallet recovery. Once you have a wallet, make sure you can restore it correctly with the seed phrase on a secure backup device before putting any serious amount of crypto in it.
Sometimes people forget to plan for inheritance. If you become incapacitated, your trusted family members should have a safe method of accessing your recovery instructions without exposing your funds to theft.
One of the best ways to keep crypto safe is to keep it offline from online threats to digital assets. Users can greatly reduce the chances of hacking or unauthorized access by keeping private keys disconnected from the internet.
The best setup for most investors is a hardware wallet with seed phrase backups that are well protected. It’s a little more of a hassle — but the security boost is well worth it when you’re securing long-term crypto holdings.
