That is a burn address, what would a person do with the address if they can't access any BTC in it?
That sure is a brun address(with hash all 0's) but what I actually meant was interesting address that has something unique like 1QBDLYTDFHHZAABYSKGKPWKLSXZWCCJQBX which has all caps or something similar.
Whats the meaning to sell a bitcoin address when you are not safe to use a bought address because someone else can spend your money. The best way is to generate yourself the address and use only you.
No, someone cannot spend your money.
For instance, let's take an example of bitaddress.org, You can't actually generate the desired vanity address until you have both the partial-private keys. You merge them and then you get a new private key which carries the address of your choice. The third party never has access to your partial-private key, so he never has access to your vanity address private key.
