I am restoring a backup of my Bitcoin Core wallet on a new PC. I downloaded the complete
bootstrap.dat and placed it in
~/.bitcoin. I thought using the bootstrap would make things faster, but importing from disk seems just as slow. Oh well.
Anyway, currently Bitcoin Core has imported blocks through Jan 2014. I made bitcoin transactions after Jan 2014 that aren't reflected in my wallet. That is to say, I have a higher balance available in my wallet than I really should.
Could I double spend these coins by sending them to another bitcoin address that I own?
