Gold

You pay a premium when buying and selling gold, in addition to a storage fee. For buying gold, the premium is 0.5% of the amount you buy, and for selling gold, the premium is 1% of the amount you sell. Insurance and storage fees are waived for all users when buying the first 20g of gold. For all holdings above this amount, you pay our standard fee of 0.0125% per week of the total amount you hold. The amount will be calculated daily and is deducted from your respective metals wallet on a weekly basis (if the wallet balance is 0, no fees are deducted).
