Are you also a "super n00b" on Ubuntu? If so, you should make sure to understand what you're doing before funding the wallet with any substantial amount.
Yes, this is the first time i am using ubuntu solely for the purposes of trying to run a node to take custody of btc myself. im trying to learn. seems like this is the method least reliant on others, but it seems fairly cumbersome and tedious.
Ubuntu will show this as Trash in the file manager, with a trash bin icon. The real question is how you managed to trash your backup without knowing it!
yes, great question. i have no idea. i simply used the file>back up and then copied those files to a flashdrive. thats why im on here, trying to figure all this out. its not all exactly straightforward, but i appreciate folks responding here.
If your "hold wallet" is cold storage, for instance a paper wallet, a single address is indeed easy. But it's better for privacy to use a new address each time, and it's less risky to use a different paper wallet each time you add funds. That way you don't expose all your funds when you want to send a small part of it later on.
but isn;t a single address how these hardware wallets work? im way more nervous about having 50 different address and key pairs and losing 1 or more than keeping up with and securing a single address and key pair. but again, im trying to figure this all out and not lose any coin in the process.
I've never used Bitcoin Core's File > Backup Wallet... feature, but instead always just manually copy my wallet.dat (ideally when Bitcoin Core is not running). I create all my backups on a file system level, so I see no reason to make an exception for Bitcoin Core.
It is good practice to actually test your backup before relying on it. Testing is as simple as running it in Bitcoin Core.
so i can test the wallet backup in btc core without having to have a second computer running core?
