For this reason, it’s very important to double- or even triple-check the address that funds are being sent to and ensure that it’s correct. One should never send funds to an unverified company or unknown individual, as there have been countless Bitcoin Private Keys instances of crypto fraud. Specifying different index numbers will create different unlinkable child keys from the same parent keys. Repeating the procedure for the child keys using the child chain code will create unlinkable grandchild keys.

What is a Public Address (or key)?

• The best way to safeguard your keys is to use noncustodial cold storage, a method that removes your keys from accessible devices and connected wallets.
• Users can make as many public addresses as they want to receive bitcoins.

An almost 50% reduction in public key size can be realized without changing any fundamentals by dropping the Y coordinate.

How Much Bitcoin Is Lost Forever and How Did It Get Lost?
