There are no examples of what the point of the feature is or description of what the feature actually is in this thread except
"Buckets are an accounting feature which allows app owners to create more in depth features."
But then he said to you there are no advanced features.

The api docs don't give any details of what they are for either (just a heads up, some errors in doc regarding param names)

It seems to be that an app can create a "bucket" to move funds into and transfer funds to players.
I don't know why you need some new feature to do that though since you could always transfer funds to players right?

I think the point is that as an app owner you can create "buckets" and name them like "Faucet" or "Btctalk promo".
Then you fund them with the amount you wish to use for these promos.

You then pay the faucet or promo from the bucket and then whenever you need to calculate your profit/loss you can see the expenses
labelled by buckets. Like you would see you spent 1btc on faucet etc.

That's just a theory based on the fact he said it was an accounting feature.

IMO it would have just been easier in this case to have an extra description field on p2p transfers where you could specify the transfer was for faucet or whatever.
Then allow you to view all transfers and group by description.

But I'm probably missing something here.

Maybe Craig will give a better example of what this if for and how it is useful.
