Publicly appreciating @MateoSoso, who has been providing very practical feedback to improve my stablecoin card ROI calculator, soon to be released to the public, for now only for the ones providing 10x feedback
@AriEiberman looking good!
One more comment: the FX applies only to the % of transactions conducted in a currency other than the one in which the card is issued.
Maybe you could add another variable (of course, the dashboard user could use the weighted avg if not)
@AriEiberman A V1 could work just by adding the cost of maintenance per card. This * N of active users gives you a proxy for the total cost for manteinance of those cards at least.
