I recently read about the fact that the techniques used by hackers to hide their identity are becoming more and more innovative and the last one seems almost impossible (very hard) to solve:
Botnet is using Bitcoin blockchains to hide CC (command-and-control) IP servers !
And taking into account the method used and how to resolve an IP by extracting it from a wallet address, I have already drawn a very interesting conclusion:
A bitcoin wallet can be considered a kind of DNS and its content can become a Web Domain and an IP, something similar as Unstoppable Domains, Namecoin, Butterfly Protocol or Handshake !
Who knows, maybe in the very near future you can do the same conversion wallet to domain/ip with any other cryptocurrency (virtual currency) !
But more details about this type of botnet can be found here:
