Hey there,
I recently dug up some of my old wallets of which I thought they were empty. I was going to delete them instantly (as they were empty anyway), but I decided to restore my wallet and let it re-sync.
Long story short, it suddenly deposited a few hundred dollars worth of BTC in my wallet.
For everyone that has Multibit HD (or Classic) wallets, you can restore it by doing the following:
1. Open up your Multibit wallet
2. Click on: Manage wallet
3. Click on: Recover wallet
Most of you might already know about this, but consider it as a reminder that something could always go wrong.
Maybe you'll get lucky, like I did.
Peace
I lost some wallets in the beginning but now I save them all on 2 external hard drives just in case my pc crashes again.
I never delete old wallets myself because I never know if someone send something to one of my old addresses.
And making back ups regularly goes without saying for most people I guess.
Having wallets on external hard drives is a smart thing to do as well, as long as you encrypt the corresponding files of course.
For most of us, making back-ups goes without saying, but you'll be surprised to know how many people don't back-up their computers (or important files) at least weekly.
I just thought I'd create this topic to bring some attention to the topic that you could possibly lose money that could be used for important things, like paying your medical bills.
