What are the chances of anyone accidentally creating the same Bitcoin address? Is it remotely possible or there is some kind of checks before the network, software, God or something would do a check first before approving the Bitcoin address? Again, I'm just thinking out loud. Hmmm...🤔
It's not possible because you as a user can not create a Bitcoin address without going through verification and confirmation of the validity of the address before authentication, so don't be so gullible not to notice the error message of the address if not valid or valid to an already existing wallet.
So just forget to think that way and try to invest your time into more advance knowledge about wallets and wallet securities.
