(5) Use trusted exchange and wallet.
A well-chosen point because some people don't even know how to distinguish between good and reliable exchanges, and it's always good to make good consultations in terms of selecting but exchanges and wallets, and there are good wallets and exchanges that will give you exactly what you want in terms of security and other features.
Do we have any trusted exchange? because I know you mean centralized exchange because that is what newbies are using mostly because they find it easy to use and are not afraid of KYC just because they want to get involve in cryptocurrency activities.
Avoid leaving your crypto investments and bitcoins in an exchange, take the exchanges both centralized and decentralized exchanges as a marketplace to trade, buy and sell your Bitcoin.
The truth is that exchanges cannot be trusted, but they can be avoided. I believe it is preferable to deal there and then retain your assets in your private wallet. The kyc is one of the factors deterring many people from participating in exchanges. There is a wallet available, and if your assets are in your wallet, you will be able to see them at any time, with no third-party story. And this are little tricks that can save a lot from scams and privacy exposure and trusting exchanges.
