Recently in Brazil we were a bit orphaned of exchanges with the instability of the service of Foxbit (Largest exchange of Bitcoins in Brazil). So I tried to use the BitINKA exchange service. I tried to sell some Bitcoins that were in my wallet. So I sent it to BitINKA. There have been 3 confirmations, 6 confirmations to now are in 20 confirmations and Bitcoin has not yet been credited to my account. I've triggered their support. They have been checking, but I'm very disappointed with this service.
So here is my doubt. These receiving exchange address are dynamic addresses. New addresses are generated with each deposit. How can I prove to BitINKA that my deposit was made correctly? I always pay close attention, I check the shipping address.
