One thing keeps me puzzled. The contents of wallet.dat do change (additional data added) upon new btc address/keys creation right?
If you have a wallet.dat file stored somewhere in a safe and not used for a few years, and you actually use another wallet.dat (a copy of the safely stored one), what happens once you decide to bring up the safely stored wallet.dat on a different PC after some time?
Do you have all your funds or only the funds that you gained with the old keys available on both wallet.dats?
I believe the keys (addresses) don't change when you are sent money, so the wallet you have stored in a safe would remain the same after years of sending it money. The wallet that you use to send money would be updated though. That's what I've read around here at least
