Well send your Bitcoin within 15 minutes of payment approval or your next transaction is Fee FREE!
Does this mean you'll send a transaction with enough fee so that it will get one confirmation within the next 15 minutes, or you'll send the tx with whatever fee it is within the next 15 minutes?
As a customer, I'd love it if it's the first one.
We guarantee that they will be sent within 15 minutes. Policy is that orders are sent instantly and we cannot control the speed at which transactions confirm on the blockchain - but we always add a network fee considered to allow confirmation within 1-3 blocks.
