You can see the benefits of each rank on this page. As for the free BFG boxes, users from rank 2 and above can get the same number of BFG tokens as it was before the update.
Thanks, but I am familiar with that page. To bad it does not show all benefits will rank 1 user get if he levels up. I mean when I am rank 2, I will get an access to daily tasks. Does rank 2 and rank 3 have different tasks and rewards? I know that in Fury Wheel I will start to receive other than FunFury altcoins, and the amount received differs from rank to rank. I mean like a fully detailed rank review. Not just at rank 2 you will get this, at rank 3 this and that. I suppose users dont fully know the benefits they will get when, that is why they dont bother much leveling.
