I have a bit of bitcoin lingering in an old bitcoin wallet (circa 2011). I just restored it from a backup but I can't seem to load it into bitcoin-qt.
If I launch the app, shut it down, the copy in my old wallet.dat file and re-open, it shows a zero balance.
If, instead, I shut it down, copy over the entirety of my old .bitcoin folder, and then re-open, I get an immediate segfault. How screwed am I?
wallet.dat; everything else should be unnecessary. Has your new installation finished syncing with the network? Have you tried-rescan? Also, was your oldwallet.datencrypted? – Nate Eldredge Jan 12 '16 at 04:05
