Storage Fees Calculation
I am trying to understand storage fees. Essentially I want the formula for the amount of gold I need to buy per month to avoid storage fees. Ideally there would be a chart/visualisation in my holding page which says that I have to incur this amount of transaction fees to not pay a storage fee. But in the absence of such a feature I am trying to work this one out, but I can't.
On the first day of April, I was charged storage fees on my Australian Dollar balance for the two vaults that I hold gold at. In that month I then proceeded to purchase gold. So when do my storage fees get credited?
On the first day of May I didn't have any fiat currency, and it appears that 0.001gg are taken from each of vault holdings. But one holding has a lot more than the other, so I don't get why 0.001gg are taken from both.
Any insights into this would be helpful.
I am posting here so that knowledge about this can be shared. But if not appropriate I can always ask my RM.
