user44683: I have a bitcoin wallet. There is not much money in it, and I do not want to run bitcoin-qt all the time.
I have a question. If I save it securely, so I can recover it at any time, but do not run it actively with bitcoin-qt, does the wallet go stale?
In other words, if, hypothetically, I have my wallet.dat safely in a file but without any software actively running it, will I be able to reinstall bitcoin-qt after an arbitrarily long period of time, read wallet.dat, and use the money stored in it?
Or will it somehow be completely out of sync?
Thanks
