As Qv said, the event itself is heavily unbalanced & can lead to a terrible headache if you let it but if you are able to do it with some one at your own power or higher to carry you, it's definitely worth the effort, before the update it wasn't the most essential thing & the headache of doing it wasn't worth the reward- that said, it is now 100% worth doing due to the amount of Sun & Moon coins you can obtain through it each week, especially if your group has done the R&D research to reduce the time it take for victory boxes to renew.

So I'm doing this from memory but I believe each box gives roughly 25-35 Sun Coins & about 250 or 450 Moon coins, each box resets every 12 hours? Which might change due to R&D research.

I guess that would mean doing it daily & completing the requirements you could roughly earn about 500~ or so Sun coins & about 5000 to 10000 Moon coins a week- obviously this isn't 100% accurate, DB is closed now & I'm just guessing the numbers but they're roughly accurate, this doesn't count in the different boxes you can get at different ranks for Ninja Fragments.
