ճԹϺcurrency investments demand strong security measures to safeguard them against cyber threats and human error. A crypto “cold wallet” or offline wallet is like a Fort Knox in your pocket, creating an insurmountable wall that hackers can’t climb over.
For Canadians, particularly those involved in Over-The-Counter (OTC) trading where discretion and protection matter more than ever, cold wallets are a practical and straightforward option.
However, having only advanced tools is not enough to keep your investments safe. You also need to know how to use them, adopt smarter security habits, and stay ahead of potential threats.
In this guide, we’ll be looking at the basics of crypto security, from understanding hardware wallets to following effective practices so you can protect your assets with confidence.

Professor of Computer Science Gene Spafford , “The only truly secure system is one that is powered off, cast in a block of concrete and sealed in a lead-lined room with armed guards.”
In the crypto world, the cold wallet is about as close to that as you can get (concrete and lead-lined walls optional), but they’re not all created equal. Broadly speaking, storage options fall into two camps: hot wallets and cold wallets.
A hot wallet is connected to the internet, prioritizing quick access to your funds but also leaving the door slightly ajar for cybercriminals. A cold wallet, on the other hand, stays offline, acting like an impenetrable fortress that’s hard for malicious actors to breach.
Cold storage is the practice of keeping your cryptocurrency completely disconnected from the internet. You can think of this as “air gapping” your valuables from the digital world entirely. This is often done with physical tools such as hardware wallets (USB-like devices) or even as low-tech as a paper wallet (yes, literally storing private keys on a piece of paper).
Without any online connectivity, hackers aren’t left with anything to “hack into.”
Here’s the core idea: private keys are the cryptographic codes that unlock access to your crypto stored on the blockchain. If someone were to get a hold of them, they’ve essentially got access to your crypto too. By keeping these keys offline, cold storage keeps them out of reach of cybercriminals.
Modern cold wallets rely on these private keys and what is known as a “seed phrase.” Seed phrases are essentially a backup plan in case something goes wrong. These 12-24 randomly generated words can restore your wallet’s private keys if the device itself is lost, damaged, or stolen.
Seed phrases should be stored in geographically distinct locations for redundancy in case one set is lost. For OTC traders and those working with large amounts of cryptocurrency, it is absolutely vital to take care of both the wallet and its seed phrase.
Whether hot or cold, crypto wallets are part of a decentralized system, this means they can operate independently of banks or traditional financial institutions, putting the control squarely in your hands.
Each wallet creates a unique address that acts like an account number with a traditional bank. The catch here is that if you forget your “PIN” (your private key), there’s no customer support line to call to get it back. This is why keeping your private keys secure is so important.
Of course, this lack of centralized oversight is what makes cryptocurrency trading so appealing. It means that while there is more privacy and autonomy, there is quite a degree of personal accountability. If you lose your wallet's private key, the assets it was protecting are now gone.
Cold storage drastically reduces the risk of accidental loss and theft and offers a much safer alternative for those who are serious about protecting their crypto. That’s why at Newton OTC, we keep 80% of our holdings offline in cold wallet storage, meaning you can trade confidently without constantly looking over your shoulder.

Secure crypto solutions come in all shapes and forms, each with its own perks and pitfalls. Whether you value ironclad security or need something that’s more convenient for frequent trading, picking the right one comes down entirely to your needs.
From hardware wallets and desktop options to old-school pen and paper, the better you understand these tools, the better equipped you will be to protect your digital assets.

Hardware wallets are essentially tiny vaults you can carry in your pocket. These physical devices, like the or , are built to keep your private keys offline, shielding them from digital snoops and hackers.
Transactions are signed directly on the device, so your private keys never actually leave this secure environment, even if you happen to plug them into a device that is itself infected with malware.
For those trading high-volume crypto OTC, this balance between convenience and security is an ideal choice. Hardware wallets are portable and durable and generally have the added layer of PIN code and seed phrase-protected security. The most serious traders often pair a hardware wallet with a water- and fire-proof safe to form a nearly impenetrable defence system.
A paper wallet might sound old-school, but it’s still a valid (though risky) cold storage solution. It’s essentially a hand-written or printed-out version of your wallet’s public and private keys, and because it’s offline, it’s safe from cyberattacks.
This analog wallet does have its own set of vulnerabilities. Paper can rip, fade, get wet, or simply be misplaced. Printing keys in plain text or via a QR code also carries the risk of exposing the keys via the printer’s stored memory or the device used to print them.
That said, paper wallets are still a useful long-term cold storage solution if you take the right precautions. Storing the paper in a fireproof and waterproof safe is a must, and handling them as though they were sensitive legal documents minimizes the risk of loss or damage.
A desktop wallet is installed on your personal computer and offers more control than a cloud-based exchange wallet but less security than a dedicated cold storage solution.
They are a good middle-ground option—great for traders who need more frequent access but still want a layer of autonomy. However, desktop wallets aren’t foolproof. Malware, phishing attacks, and even hardware failure can expose your keys. Some of the more reliable and popular desktop wallets include , , and the Bitcoin-only .
For those managing smaller holdings or actively trading and using a desktop wallet, you should also ensure your system security is up-to-date and actively protecting your computer.
For those who need quick access to their crypto wherever they happen to also have their smartphone, mobile wallets offer unmatched convenience but at the cost of increased vulnerability. Just like your smartphone, these wallets are always online, so they’re susceptible to hacking, phishing, and physical theft if your phone is stolen.
While it’s generally safe to store small amounts of crypto in a mobile wallet, they shouldn’t be used as your primary storage if you’re holding onto large volumes. If you do choose to use a mobile wallet, ensure the application and your phone are secured by a password or biometrics.
Popular mobile wallets include the , the custodial , and , which supports thousands of blockchain assets.
No matter which storage method you decide on, a physical safe is a wise addition to your security layers. A safe protects your cold storage wallets from theft and natural disasters like fire, flood, and even electromagnetic pulses.
Choose a high-quality safe designed for sensitive items such as documents and electronic devices, and if you’re extra serious about your crypto security, have the cold storage devices and their seed phrases stored in geographically separate locations.
Cold storage is by far the best and most secure way to store your cryptocurrency, but it’s only as good as the setup and security hygiene behind it.
Whether you’re a casual investor or dealing with high-stakes OTC trades, the steps you take to secure your assets will determine how effective your cold wallet is.
Here is how to make cold storage work for you safely and efficiently.
Getting started with a Bitcoin hardware wallet (or any cryptocurrency) in Canada is simple, but the process requires a sharp focus on the details to avoid mistakes.
For those just starting, Newton provides an easy and safe way to buy and manage cryptocurrency. It’s an ideal place for Canadians to start funding hardware wallets securely.
Moving your assets from a trading platform to a cold wallet is a straightforward and essential part of securing your cryptocurrency.
If you plan to use or are already using a cold wallet, it’s a fantastic start, but keeping it secure means layering additional safeguards.
If you’re using an OTP authentication app like Google Authenticator, ensure there is a cloud-based backup of your codes in case you lose your smartphone.
If you’re trading high volumes of cryptocurrency to and from a cold storage wallet, Newton’s OTC platform provides a white-glove and secure environment for $30,000+ private trading.
