Frequently Asked Questions

What is a hot wallet?

A hot wallet is a cryptocurrency storage solution that maintains constant or frequent internet connectivity, enabling quick access and transactions but potentially exposing private keys to online threats. Examples include exchange wallets, web wallets, mobile wallets, and desktop wallets that are connected to the internet.

What are the main risks of hot wallets?

The main risks include malware and viruses targeting private keys, exchange custody risks, phishing and social engineering attacks, technical vulnerabilities in wallet software, network security risks, and user error. Hot wallets are particularly vulnerable because they maintain internet connectivity, making them accessible to various online threats.

How can I protect my hot wallet?

Protect your hot wallet by using strong, unique passwords, enabling two-factor authentication, keeping software updated, using reputable wallet providers, avoiding public WiFi for transactions, being cautious of phishing attempts, using antivirus software, and limiting the amount of cryptocurrency stored in hot wallets to only what you need for immediate transactions.

Should I use hot wallets for large amounts?

No, hot wallets should not be used for large amounts. Professional security frameworks recommend limiting hot wallet exposure to transaction amounts only, while maintaining 90%+ holdings in cold storage systems. Hot wallets are suitable for small amounts needed for daily transactions, but significant holdings should be stored in hardware wallets or other cold storage solutions.

What's the difference between hot and cold wallets?

Hot wallets maintain internet connectivity and are convenient for frequent transactions but more vulnerable to online threats. Cold wallets (like hardware wallets) store private keys offline, providing maximum security but less convenience. Hot wallets are suitable for small amounts and active trading, while cold wallets are ideal for long-term storage of significant amounts.
