What do I do with all my lingots?
Spend them a the store, but I think it's a waste of time though. Sometimes when you complete a level it asks you if you want to pay 5 of your lingots to get a 7 day streak, even if you are not there. I hoped this helped.
You could buy the few things that are in the lingot store, or host an xp contest....or just do what I'm doing and just watch the amount grow and grow and see how high you get :) and occasionally give some away if you want.....that's about it for now.
you can give tham to people that what to get things from the lingot store but do not have the right amount !!!
Give them to newbies who might want to buy something at the store.
