unless you want to update the blockchain or send/receive funds right?
I need to look into this more. I only trade ~500 euro at the moment so I have it stored at one of the exchanges with 2FA protection which is currently enough, but as a negative, I've never looked closely at software wallets on my own PC (past the setup) but I didn't play around much with backing up the private keys, viewing said keys or running through recovery if you have a copy of the private key but lose everything else...
I'd be terrified of the 'I forgot my password' as well although I take measures against that as well, but I feel like enthusiastic users could manage to lock themselves out of their own wallets in the interests of making it 'super secure' and accidently make it so secure that it's too secure to get into themselves.
The solution of course is a couple of guides and some run throughs of situations with empty wallets and testing, but to do this properly this would take me a couple hours I don't have at the moment.
As an aside, Multibit bitcoin wallet doesn't seem to have to download the whole blockchain like the LTC wallet does. why not?
