What happen with my BPP?
At 12.03 i have more than 40k bpp. Today i start 1.1.9.9g wallet and i have only 4 763 bpp.
I tried to restore the wallet from 2019-03-12-13, but the balance is the same
There's a good chance you were on the fork while earning those coins .. You can try to use the rescan option in "wallet repair" section of the menu
No, most of the coins were received a very long time. But I have a suspicion that when I did "tithe" - the coins moved between to "tithe" addresses. And now they just can not see (or cleared).
