In this post, I want to talk to you about a fundamental aspect of cryptocurrency security: wallets. As the crypto world continues to expand, users face a crucial question: how can they store their digital assets securely? The choice between a cold wallet (offline) and a hot wallet (online) can make a significant difference, especially when it comes to protecting your cryptocurrencies in the long term.
In this article, we’ll briefly explore what each type of wallet is, some examples of both, and the importance of choosing cold wallets to avoid fraud and losses, as happened with the collapses of FTX and Celsius.
What is a Hot Wallet?
Hot wallets are those that are connected to the internet, allowing for quick access and the ability to make transactions at any time. They are commonly used on exchanges (cryptocurrency trading platforms) or mobile applications, with their main advantage being convenience. Some popular examples include:
- Exodus: A hot wallet with a user-friendly interface.
- Metamask: Very popular among Ethereum users and decentralized applications (DApps).
- Coinbase Wallet: Associated with the Coinbase exchange, facilitating transactions between accounts on that platform. However, their constant internet connection makes them vulnerable to cyberattacks, which could lead to losses if the necessary precautions are not taken.

What is a Cold Wallet?
On the other hand, cold wallets are entirely disconnected from the internet, providing an additional layer of security. These wallets typically come in the form of physical devices, like USBs, that store private keys out of hackers’ reach. Some popular examples include:
- Ledger Nano S/X: A physical storage device widely used to hold cryptocurrencies for the long term.
- Trezor: Another physical wallet offering high levels of offline security.
Because of their offline nature, cold wallets are considered the safest option for storing cryptocurrencies, especially large amounts, over long periods.
The Importance of Owning Your Cryptocurrencies in a Cold Wallet
One of the most painful lessons for the crypto community was the collapse of platforms like FTX and Celsius in 2022. Thousands of users lost access to their cryptocurrencies, which were stored on these centralized exchanges when the companies declared bankruptcy. Without owning the private keys to their funds, many users saw their life savings disappear.
This highlights a fundamental rule in the crypto world: “Not your keys, not your cryptos.” When you store your assets in a hot wallet managed by a third party, you delegate custody of your cryptocurrencies to that platform. If that platform goes bankrupt, gets hacked, or faces any other issues, you could lose part or all of your funds.
In contrast, with a cold wallet, you have full control over your private keys. This means that no one else, not even an exchange, can access your funds. In the long term, this strategy minimizes the risk of losing your cryptocurrencies due to third-party fraud or bankruptcy. While it’s possible for a cold wallet to be compromised, it usually happens due to improper use by the user or interaction with questionable platforms.
In conclusion, both cold and hot wallets have their place in cryptocurrency management. Hot wallets are ideal for quick, everyday transactions, while cold wallets offer greater security for those looking to store their assets long term. Learning from the mistakes of those who suffered during the collapse of FTX and Celsius, it’s essential to consider a cold wallet as a key tool to protect your crypto wealth if you’re investing for the long term.
