But when considering fiats, crypto currencies are basically safer by its cryptography security feature. No random hacking will be possible. Similar to fiats, we must secure our assets in cryptocurrencies with a strong password and other security measurements like 2fa. Bitcoin is stronger a bit than fiats or gold or any similar assets against robbery/hacking.
I guess you are confusing different matters here. Namely, hacking with stealing. To hack a fiat currency, you would need to break into a Central bank's servers. How are you going to do that if these servers may never be online? Even if you succeed (purely hypothetical), your "hack" will be reversed in less than no time once discovered. On the other hand, stealing Bitcoins from desktop wallets is a usual thing nowadays...
And no two factor authentication will help you in that case
Hacking and stealing of course is different but have some similarities, if you want to be take it literally so be it, i
s FIAT currency will be stored forever in the Central bank? I think not, it must be circulated. We can't steal bitcoin with our bear hands, breaching to the system or hacking it then stealing will do. Stealing information is consider hacking, hacking information is consider stealing, so My friend which is which
I heavily suspect that you implicitly assume that fiat currencies circulate like Bitcoin in Internet, right? Then you are in for a big surprise. The fact that you can use Internet banking to send money to other people (in fact, only to give bank an order) as well as pay bills or orders through Internet (again, only give orders) has nothing to do with how fiat currency circulation is organized...
