3. What types of cryptocurrency wallets are there?
Answer: Cryptocurrency wallets can be broken down into:
Hot wallets: connected to the internet (e.g., mobile wallets, desktop wallets, web wallets).
Cold wallets: Offline wallets, such as hardware wallets and paper wallets.
4. What is a hot wallet?

7. How do I choose the best cryptocurrency wallet for my needs?
Answer: Consider factors like:
Security: Hardware wallets offer more security than software wallets.
Convenience: Software wallets are more convenient for frequent use.
Supported currencies: Ensure the wallet supports the cryptocurrencies you use.

Answer: A public key is like an address to which others can send cryptocurrency. It can be shared freely, and it does not allow others to access your funds.
9. What is the private key to a cryptocurrency wallet?
Answer. A private key is a unique secret code enabling access to all funds in a wallet. There is a demand to keep private keys safe as anyone who manages to get into your private keys can control those funds.
10. What does a seed phrase mean in crypto wallets?
Answer: A seed phrase or recovery phrase is a set of 12 to 24 words that your wallet generates. You will use this when you have lost access to your wallet, thereby making it essential to store the phrase safely.

Answer: Two-factor authentication (2FA) is an added security layer that requires a second form of identification, like a password and a code that will be sent to your phone, to get into your wallet.
12. Can I retrieve my cryptocurrency wallet if I lose my private key?
Answer: If you lose your private key and you didn’t back up your wallet with a recovery phrase, then you won’t be able to access your cryptocurrency. That is why it’s important to back up your seed phrase.
13. How would you store a seed phrase best?
Answer: The best way to store a seed phrase is offline in a safe place, like a safe or a safety deposit box. Never store it digitally or online, for the reason of hacking or stealing.
14. Are cryptocurrency wallets anonymous?
Answer: Crypto transactions are a bit private. However, transactions are not perfectly anonymous. Their public blockchain address is visible to anyone, which means that there is a track of transactions performed. Some wallet services offer extended privacy features but true anonymity becomes difficult to claim.
15. How do I send cryptocurrency from my wallet?
Answer: To transfer cryptocurrency, you need the recipient’s public address and the amount of cryptocurrency you want to send, which you will then authenticate with the private key of your wallet or the password.
16. How do I add cryptocurrency to my wallet?
Answer: You can receive cryptocurrency by providing the recipient with your public key or your wallet address. They use your wallet address to send you cryptocurrency.
