I've made two smaller Atm btc purchases in the past and paid what I'd call exorbitant fees! I understand there's a convenience fee involved with using an atm and I can accept that to some extent but I'd like to know how to determine what the fee will be ahead of time so I can at least walk away with the right amount of btc and not have to make two purchases and get hit with fees twice in order to walk away with the needed btc. So my question is how do I determine the TOTAL FEES I'll be charged? I have two different Coin Source ATMs close by and several Coin Momma ATMs a fair distance drive away. Can I research these online for the fees? Do I have to go to the physical ATM to see the fees? Are the fees different from location to location for the same source (Coin Momma for instance) even if they are located across the street? From reading Google reviews of each location I believe so but not sure??? For simplicity sake say I input $100 cash into a BTC ATM how much btc will I walk away with and how do I determine that even ballparkish from various btc ATMs?
