POS now is 5% or already 1%?

I am going to say unlikely hacked. What is more likely (I have received scam/spam like this), they send to a bunch of similar looking addresses. i.e. bct_all@here.com, bct_a11@here.com, bct_anon@here.com, etc.
I think if it was a hack of DeepOnion email list that everyone would be getting the same emails.

Our forum secured by experienced IT engineers.  We have not been reported & informed before about such an incident. We monitor also unique emails so far we have not seen any spam emails to them.
The email providers exploits, or random or systematic address emails can also be spammed.

You can come and share in DeepOnion forums the email you received. If any others also receive similar emails they can confirm the leakage.


It is  now 1%

Email providers are also known to share user data with third parties that are bound to respect the rules and not compromise the privacy of the users. We all know how it worked with the Cambridge Analytica scandal 

Btw, I asked my manager about that jokingly of course(My employer is big tech corp) and he said "Yep, maybe your kids will catch that wave"

You may want to check the tutorial section at DeepOnion forum, or try this one?

Also, make sure you are using your backup file in the new installation, otherwise if you only have the newest version but your backup file is not in the DeepOnion folder, that might be the issue or reason you see zero balance.

For the new DO versions, where the wallet file should be? inside DeepOnion folder or inside wallets folder only?

So where the wallet.dat file is? Or we don't need this file too?

If that's the case, then the wallet.dat file should be where it always was. I haven't updated yet and it's in that place on my computer.
