I have an old wallet.dat file (from a backup) and no client installed since a very long time. Recently some transactions have been made (BTC have been sent to my address).
Will this old wallet.dat file allow me to be the owner of the new money? I’ve read that 100 private keys are generated in advance and are in stock of the file. Does that mean, that I can receive 100 transactions after taking my client (it was bitcoin-qt/bitcoin-core) offline? Or what are these 100 keys for?
