I’m running Reddcoin core on an outdated version of OS X (10.11), it crashed twice while syncing, and OS X must’ve restarted itself yesterday, but my fears were absolved when I opened up the wallet again and staking did not lose any progress. I imported the previous bootstrap file from a long time ago, and it only took me 2 days (after the crashes) to fully sync.
Don't mind my signature, there's probably more important info in the text above it.
```NEVER send your wallet to someone offering that they can recover your coins. There's a huge chance that you will never see them again!```
