How come some addresses show up in search results while others don't? Some Bitcoin wallet addresses can be found by google, but some others shows no result. For example, this wallet is visible on many Bitcoin websites and google has a lot of results 1ENFY4h7ntGZbqwcwpQtXVFJrPnfXRHQLe and we can see its transactions. But this other address 126kUxBmdLTk4M7w1uaQ2pjAhm9KbZ6dxp (a ransom-ware wallet!) has no result. How it is possible? How can people do this?
The latter address does not show up in google because it has not been used for a transaction yet. Once someone sends money to it, it will show up.

It's possible that we'll be able to create systems in the future that don't have this problem, but don't hold your breath.
