We're talking about VPNs and blablabla. What if you make a transaction, using cafeteria's free Wi-Fi? I think you would be covered...
Simply we can't hide anything with this. That is why I'd never used free-wifi when accessing my wallet and for security reasons.
We can hide identity in crypto but not the numbers of Bitcoin we are holding in a certain wallet. Once we have a record in the blockchain technology, everything is traceable even we use a VPN or whatever it is to bypass IP. But does it give the interest of everybody? Not at all, Maybe if we are holding a lot and that will get attention especially for the hackers/scammers. But for those ordinary Bitcoin holders, I don't think so.
