Why You Need It: With hacks and scams on the rise, knowing how to properly secure your crypto holdings is critical to protecting your investments.

So, you’ve finally bought some crypto. Congrats! Now comes the fun part: figuring out where to stash it. Should you leave it on the exchange (like Binance or Coinbase) or move it to a wallet? Let’s break this down like a toddler smashing a piñata—messy but effective.

First we’ll point out that all crypto exists somewhere on a wallet address on the blockchain. Wallets are used to interact with the crypto. Buying, selling, swapping, and transferring are all transactions that will change the amount of the crypto on a wallet. Interactions that change the balance of your crypto are barred from use without presenting a public key and a private key to a hot wallet host that is online.

Exchange vs. Wallet: The Hotel vs. Your House

Leaving crypto on an exchange is like renting a hotel room. It’s convenient! You can trade, swap, and grab a crypto cocktail (metaphorically). But here’s the kicker: you don’t own the keys. If the hotel gets robbed (cough FTX cough), your stuff’s gone. Another analogy is that an exchange operates like a bank. A bank may have $3 billion in deposits stored in one place. There’s no government transaction when you deposit or withdrawal money. There’s no blockchain transaction directly related to your transactions on an exchange either. Your transactions are handled within the assets being held and managed by the institution. Having a wallet makes you the bank, allowing you to interact with the blockchain directly.

When you buy crypto on platforms like Coinbase, Binance, or Kraken, your funds are automatically stored in a wallet that is managed by the exchange. This is convenient because you don’t have to worry about managing private keys or security settings. However, leaving your crypto on an exchange comes with some risks.

Pros of Storing Crypto on an Exchange:

• Easy access for trading and transactions
• No need to manage private keys
• Some exchanges offer insurance for certain types of losses

Cons of Storing Crypto on an Exchange:

• You don’t truly own your crypto (the exchange holds your private keys) so you’re relying on keeping up your password and access methods to view their representation of your holdings.
• Risk of hacking and exchange failures (e.g., Mt. Gox, FTX collapse)
• Possible withdrawal limits or frozen accounts during high volatility

A wallet, though? That’s your house. You hold the keys. No shady landlord (or exchange CEO) can lock you out. But just like houses, wallets come in different flavors—some safer, some… less.
Wallet Types: From Paper to James Bond Gadgets

Keeping some active funds on an exchange makes sense if you plan to trade frequently. Using a wallet is the safer option for long-term storage, such as your HODL coins.

1️⃣ Paper Wallets
Think of these as the pirate maps of crypto. You print your private key on paper, stash it in a safe (or under your mattress), and pray your dog doesn’t eat it.

• Pros: Offline = unhackable and there is no hardware or software required.
• Cons: Fire, water, or a curious toddler = poof, your crypto’s gone. Don’t lose the paper and don’t save digital copies or it defeats the purpose of “paper wallet”. There’s no easy way to trade or move your crypto until you import the stored wallet into a hot wallet online. After access from a paper wallet some recommend setting up a new paper wallet to revert back to cold, offline storage again. To do this you’ll need to create a new paper wallet address for each crypto and send your assets to it from the hot wallet you’re transacting from. Messy!

2️⃣ Software Wallets
Browser apps like MetaMask and Phantom.
Mobile Wallets that can be accessed from a phone or tablet.
Desktop wallets that install to your desktop or laptop computer.

These are the digital equivalent of a wallet in your back pocket but they are continually online. These are Hot Wallets.

• Pros: Easy to use, great for intermediate storage, sending and receiving crypto, etc.
• Cons: Connected to the internet (hot wallet), so hackers might poke around. Enable and use 2FA (Two-Factor Authentication) everywhere and anywhere this is offered. This can get tedious and annoying for frequent access but the additional security is well worth the trouble.

3️⃣ Hardware Wallets
Fancy USB sticks (Ledger, Trezor) that scream “I’m serious about security.” These are cold wallets—offline, baby. These are physical devices that store your private keys offline. A point to keep in mind is that a hardware wallet doesn’t hold your crypto per se, but provides access to it. Your crypto is on a blockchain address that is always out there, albeit with a really strict set of access credentials to interact with it.

• Pros: Hackers need to physically steal it and crack your PIN. Good luck.
• Cons: Costs money (but so does replacing stolen crypto).

Hot Wallet vs. Cold Wallet: Sweaty vs. Chill

Hot Wallets are connected to the internet. Convenient for quick trades, but riskier (cough phishing attacks cough).

Cold Wallets are offline storage. Perfect for long-term “HODLers” who like to sleep soundly.

So… What Should You Do?

If you’re day-trading, keep a small stash in a hot wallet (software). But for the bulk of your crypto that you plan on holding for a long time? Cold storage! Remember to investigate and take advantage of possibilities of staking your long-term coins for additional benefit. Hardware wallets are the gold standard, but even a paper wallet beats leaving it on an exchange.

Which Wallet is Best for You?

Choosing the right wallet depends on how you plan to use your crypto:

• Frequent trading? A hot wallet and also using exchanges on your phone or computer can be convenient.
• Long-term holding? A hardware wallet or other cold storage method is best.
• Small amounts for daily use? A mobile wallet or exchange may work fine.
• Super cautious? A combination of different wallets can provide a good balance between security and accessibility.

Pro tip: Not your keys, not your crypto. Exchanges can freeze accounts, get hacked, or pull a disappearing act. Wallets put you in control—no middlemen, no drama. Reputable exchanges have hefty safeguards for sure. In principle you’re just not in control and there can be risk.

Bottom Line: Crypto security isn’t sexy, but neither is losing your life savings to a hacker named “CryptoBandit69.” Use exchanges for trading, wallets for storing. And if you’re still using a sticky note for your private key we need to talk!

Now go forth, secure your bags, and remember: in crypto, paranoia is a virtue.
