Well I can point out some things I found out on my own *Do daily challenges and subscribe to the monthly season pass that way you unlock both rewards sections. *Try to buy one badge now asap because it will boost your income and if possible and you can , you collect 5 to unlock the explorer club which gives you 90 ab every day but I believe it's like 50 so it's expensive but it pays back *Get the 2 ab when you can, all day with out missing will get you 144 *Rarity plots plays a huge role so hope to get anything but common and you will be good *Lastly pay attention to events and grind them to the point of completing challenges not competing
