There are many factors influencing earnings according to the time of the year, and that includes year end holidays.
Totally normal for them to take a slight dip.
i am not talking about general comments. anybody with statistics. if anyone has same traffic as before but earning low during last 4-5 days?
I see you have not understood the a-ads principle.
Earning does not depend on your traffic.
You can have much traffic and earning nothing or zero traffic and earning much.
Your earning depends absolutly only on how much an advertiser pays you.
Is this so hard to understand?
