Can anyone help me fucking set up an offline USB wallet -.-
copy the wallet to a usb drive, auto run it from there?
Please a detailed guide. And can we just move wallet dat file? And move wallet dat file back in Appdata when we need to transfer funds?
Yes and yes, it's as easy as copying or moving it to a USB then moving it back to appdata.
And while theres no wallet dat, noone can steal anything I suppose? +1111
Only way to steal your coins is to get your private key, it's usually stored in wallet.dat with your transaction data and such. If you want the best security you'd export the private key on a PC with no internet connection and print it to a dumb-printer(Printer that can't access the internet and doesn't store printer jobs) and keep the paper with the private key in a water and fireproof safe untill you need your wallet again.
But a USB-key is fine too.
