What is a cryptocurrency wallet?
A common misconception is that a crypto wallet “stores” your digital coins like a physical wallet stores cash. In reality, your cryptocurrency lives on the blockchain; the wallet simply stores the private keys (digital passwords) that allow you to access and move that currency.
Think of the blockchain as a giant wall of transparent glass lockers. Anyone can see what’s inside, but only you have the key to open your specific locker.
The world of cryptocurrencies can feel like the wild west. Markets can react to the slightest good or bad news, and new and innovative tech comes out every month. Transactions are immutable, stakes are high, and security threats are very real.
In all of this, one thing is constant: the importance of storing your digital assets properly and safely away from bad actors. It may seem a daunting task with a long list of common scams targeting crypto users. However, armed with the right knowledge and tools, you can keep your assets secure. Of course, the most important tool in crypto is the one you use to manage your assets and store your private keys – your wallet.
The most important choice you'll make is how “connected” your wallet is to the internet.
For maximum security, it is best practice to store the majority of your assets in a cold wallet. While some users choose to distribute their holdings across multiple cold devices for added redundancy, this is ultimately a matter of personal preference. Limit your hot wallet to smaller balances intended for frequent trading and daily transactions. Think of your cold wallet as a long-term savings account and your hot wallet as the cash you carry in your physical pocket.
| Type | Connectivity | Pros | Cons |
|---|---|---|---|
| Hot Wallet | Always Online | Free, fast, great for frequent trading/DApps. | Vulnerable to hacks, malware, and phishing. |
| Cold Wallet | Offline | Extremely secure; keys never touch the internet. | Costs money ($50–$200), less convenient for daily use. |
This determines who is actually “holding” the keys to your funds.
