The cryptocurrencies are stored on the blockchain. The ownership is verified through a key called a private key.
The major difference between cold and hot wallets is about where and how this private key is stored. Let’s discover more about these crypto storage devices and explain more what is a wallet.
What is a Cold Wallet?
Cold wallets are wallets where the private key is generated and stored offline. These wallets are meant to never interact with any smart contracts or dApps.
Cold wallets are the safest wallet to safely store your crypto for the long term.
How to Create a Cold Wallet?
Get any hardware wallet like Ledger or Trezor. Generate a private key or a new wallet note down the public address (for Ethereum it starts with 0x..) and store the device safely. Now, you can send assets to the public address.
Make sure the device is never connected to the internet. The moment it does, the wallet no longer is cold. Does that mean hardware devices are cold wallets? They can be if you use the device for long-term storage only. However, if you use the device to sign transactions, the device is not a cold wallet anymore. Here is a video about it:
In summary, cold wallets lose their high safety features as soon as the private key touches the internet.
What is a Hot Wallet?
Hot wallets store the private key online, where it is generated. These wallets are ideal for trading, high-frequency buying and selling, DeFi, etc. Some examples are Metamask, Trust Wallet, Coinbase Wallet, Phantom Wallet, etc.
The biggest advantage of the hot wallet is that it is free to create one. You can download the app on your phones, or on your browsers to access hot wallets. However, the high level of convenience comes at a cost: hot wallets are highly prone to hacking and phishing. If you want to hold crypto for the long term, you can consider switching to a hardware wallet.
What is the Best of Both Worlds?
A combo of cold and hot wallets is the way to go. For this, get any hardware wallet-like ledger. If you feel like spending more money, get more hardware wallets. Create it and safely store the private key – write it on paper, engrave it on metal, carve it on rocks, etc.
Note the public address and you can send your crypto to this address for long-term storage. Now, if you only have one ledger, just reset it and create a new one. Use the new one for short-term storage and transactions. You can also create multiple software wallets like Metamask for various purposes.
