lets say that my post get 353 sats but when I open wallet statistics I see only 247.
is it taking time to get proper number?
is some kind of fee?
I have not connected "external wallet", still using custodial SN. I know that after 5.november it will be different but I not able to find that post about it ... Is it activated or it is postpone?
thanks
divide one by the other and the suspiciously round number could be a clue!

Zaps incur 30% sybil fee so that they can be used for ranking purposes.

ok, I thought so. maybe I missed it in the past but it seemed to me that the difference was not 30%. anyway, thanks again for the explanation
