The present invention concerns a cryptocurrency-cash gateway, comprising a wallet interface () for communicating over a network with at least one crypto wallet () and an EFT gateway interface () for communicating over a network with at least one electronic funds transfer, EFT, gateway or financial institution (), wherein the cryptocurrency-cash gateway is operable to perform a cryptocurrency-to-cash transaction for allowing a user to withdraw cash at an automatic transaction machine, ATM (), or a point-of-sale, POS, system (B) by exchanging a corresponding amount of a cryptocurrency from the crypto wallet(s); or conversely allowing the user to deposit cash at an ATM or POS system and exchanging it for a corresponding amount of a cryptocurrency to be deposited in at least one crypto wallet of the user.

Generating an optimized pricing plan includes accessing a hierarchy comprising a sequence of levels, where each level includes an objective function and a set of constraints associated with the objective function. A mathematical programming model representing a pricing plan problem is determined for an item group comprising items. The following is repeated for each level of the sequence of levels: selecting a level comprising an objective function and a set of constraints associated with the objective function, determining an optimized boundary for the objective function, and adding a constraint generated from the optimized boundary to the set of constraints of a next level. An objective function of a last level of the sequence is optimized subject to the set of constraints associated with the objective function to yield an optimized result. An optimized pricing plan is generated in accordance with the optimized result.
