Nu te uita la income-ul de pe canale. Acela este "estimated". Uita-te DOAR la rubrica de Payments!

What's the difference between estimated and finalized earnings?
Estimated earnings reflect close estimates of your recent account activity. Your Reports pages all show estimated earnings, so we can give you a rough idea of your recent performance as soon as possible.

Finalized earnings are accurate earnings amounts that include all revenue owed to you for all valid activity. At the end of each month, our records are processed and verified, then finalized earnings are posted to your Payments page.
Si inca ceva, cum spunea si cineva mai sus: Conversia valutara (care in nici un caz nu ajunge la o diferenta de 100 Euro, insa de obicei are un flux +- de ~ 1%): Google are o conversie, Western are si el o conversie interna.

Asta inseamna ca daca tu ai contul Adsense in USD si primesti banii in WU prin Euro, WU intai ii converteste in Euro si dupa aia ti-i da tie. Daca Adsense ii emite in Euro si ii primesti in Euro, nu exista conversie valutara.
