4. Choose a reputable exchange or broker: There are many Bitcoin exchanges and brokers out there, but not all of them are created equal. Choose a reputable exchange or broker with a strong track record of security and reliability.
This sounds like promoting the use of centralized exchanges and custodial wallets which is not really not the best practice so it's not highly recommended.
Why not recommend the use of decentralized exchange like Bisq? You are even wearing their signature.
5. Keep your investments safe: Bitcoin is a digital asset, which means that it can be vulnerable to cyber attacks or theft. It's important to keep your Bitcoin investments safe by using a secure wallet, setting strong passwords, and following other best practices for digital security.
The security of the wallet is mostly on the user. What you can do is use a non-custodial wallet and make sure you keep it in a safe place. Avoid connecting it to other apps or devices as much as possible.
