This means, that even if you are able to find an ATM that is willing to give out such an amount, in one single withdrawal, you will still have to visit the ATM several times per week to withdraw your 15 000 USD.

Most ATMs will only let you withdraw an amount between $800 - $2000 per transaction and many ATMs charge a separate ATM fee on top of the fee that paxum or FCP charge. This means that you should calculate a withdrawal fee of around $5 per transaction, to see the full cost. This can of course vary depending on country and specific ATM, but $5 is a fair number for calculation and this include the fixed Paxum ($2) / FCP fee ($2.75) ATM fee.

Since the ATM fee is charged regardless of amount you have to calculate that you'll be paying around $10 in fees per day, given that you will most likely have to make two ATM withdrawals per day to be able to withdraw your full $2500 per 24 hours.

To withdraw $15k you'd have to make
a minimum of 6 withdrawals, on 6 different days if you can get the exact full $2500 each day, at a cost of $60 plus any currency exchange losses (it is fair to calculate at least 2% currency losses due to Mastercard's exchange rates)
most reasonably, 12 withdrawals, 2 per day, on 6 different days at a cost of $120 plus again any currency exchanage losses. If you want to save some, say that you only withdraw $2000 per day, then you could get 6 x $2000 = $12 000 and then go one more separate day and withdraw $2000 and get to $14 000 and let $1000 remain in account/card and roll over into next period.

What will most likely be your hardest task, is to find ATMs that are willing to spit out enough cash per transaction. With cash being more and more obsolete in most Western countries, many ATMs will only spit out in the range of around $1000 - $1500 per transaction, but your milage may vary greatly depending on country and specific ATM.

With amounts as high as $15 000 you'd be better off with a Paxum acocunt and requesting a montly wire transaction directly t your bank acccount. It will cost you $50 fixed fee plus any currency exchange losses. It will save you from having to go to the ATM 6 or more times per month.
