Restore Wallet.dat

[Xubu]

Hi,

If someone hacks my computer or cloud and they would steal my wallet.dat file. will that person be able to build up my wallet on another computer and steal my coins when my local wallet is still up and running on my computer?

Yes. If your wallet.dat is stolen, then the thief will be able to steal all of the Bitcoin from you. It doesn't matter if you or anyone else has it open, as long as the thief sends a transaction spending the Bitcoin in your wallet before you or anyone else does, they can steal the coins. It is best to password protect the wallet with a strong password so that even if the wallet is stolen the Bitcoin cannot be stolen. Even so, if your wallet is stolen, you should move the coins out immediately.

Yes, if it's not encrypted. If it's encrypted, they'll have a hard time cracking it, but if it's not, too bad. The wallet.dat is basically a canister that holds your bitcoin. You should password-protect it and encrypt it at all times. Try using Truecrypt. Its great.

The person could just import his/her wallet.dat into their wallet file, and kapow. If there's no encryption, there goes your bitcoin! *waves*

Off couse if the wallet is not encrypted anyone who has access to you wallet.dat file can restore the wallet whatever you have the wallet online on your laptop. You need to make sure that no one can get his hands on your computer or wallet.dat file.

The build in encryption by bitcoin core is pretty good (in comparisson to other wallets). I can do ~1700 passwords per second with my GPU vs. a bitcoin core wallet. E.g. vs. multibit classic I can easily do 400kP/s on my CPU. Multibit HD is a great improvement in that regard.

You might want to consider VeraCrypt as it fixes some of TrueCrypt's bugs and is still maintained.

password 12-20 with complex symbols will protect you forever , the problem is not to lose and not to be mistaken in at least one symbol

You should be safe in the cloud, but if a hacker gets inside your computer and monitor your keystrokes, no amount of encryption will help you as he will be able to catch you typing the password through a keylogger. Therefore, isolation is needed for maximun security (cold wallet).
I would only bother if you had a decent amount of BTC, otherwise, encryption + firewall and AV if Windows user, should be enough.

Like others have already said just encrypt your wallet (password protect it). It is absolutely imperative you do this, without the password nobody can get access to your coins.

I think better If you did a fresh install and you have the latest version BEFORE you run MNC QT for the first time (after a fresh install) you will want to locate your Mincoin Folder in "%appdata%". Once you have located this folder open it up. You will see an existing "wallet.dat" file in there. Delete this empty wallet.dat file. Then drag and drop a copy of your backup wallet.dat into this folder. Close out of the %appdata% and then run your fresh installed
