Yes, there is a real risk that your private key can be exposed on the internet when using a hot wallet to transact with Bitcoin, although it doesn’t always happen.
Why is there a risk?
Hot wallets are wallets that are connected to the internet — such as exchange wallets, mobile apps (like Trust Wallet, BlueWallet), or browser extensions (like MetaMask). With an internet connection, several risks arise:
1. Malware infection: If your device is infected with viruses or trojans, private keys can be stolen.
2. Phishing or social engineering attacks: You might be tricked into revealing your seed phrase or passphrase.
3. Software vulnerabilities: Some wallets may have bugs that leak private key data via the network or device memory.
4. Seed/key entered on an online device: Once you've entered your seed on an online device, it’s considered a hot wallet and exposed to risk.
How to stay safer?
Don't store large amounts of BTC in hot wallets.
Use cold wallets like Trezor, Ledger, or air-gapped setups (e.g., Sparrow + old phone with no internet).
Only use hot wallets for small transactions, like a “spending wallet.”
Never enter your seed phrase or private key into any internet-connected device unless absolutely necessary and you understand the risks.
