<p>Yes. The two wallets 'hold' the same Bitcoin. If the thief steals your original wallet, it becomes a race to see who can spend the Bitcoin first. You have the advantage that only you know your password. (You did set a password, right? :) The thief has the advantage of surprise.</p>

To avoid this, after your wallet is stolen, make an entirely new wallet, and transfer your Bitcoins to that. That will be safe, assuming you win the race.</p>

<p>I'm thinking of buying some bitcoins. Before I do I want to be sure that I can backup and restore my wallet - Bitcoin Core. This seemed to go ok, the bitcoin loaded into the new wallet which was on a different computer from the original.

I'm thinking of buying some bitcoins. Before I do I want to be sure that I can backup and restore my wallet - Bitcoin Core. This seemed to go ok, the bitcoin loaded into the new wallet which was on a different computer from the original.
The original bitcoin wallet still shows the old balance.

I'm sure it's unlikely, but what if someone stole my computer and I then restored my bitcoin to a new wallet - would the thief be able to spend from the original wallet after I'd done the restore?
