It is good to know that even if they are using small fee per byte based on your transaction posted, it still went smooth. But their economy fee for withdrawal is 20k sats, so a lot of those satoshis go to their operation side? Just wondering about how they have fix tx fee and where it goes?
I also think about that matter at first. However, the majority of reputable exchanges use 50k sats as withdrawal fee.
https://withdrawalfees.com/coins/bitcoinWith that in mind, 20k sats feel acceptable (for me), and I received the payment in a relatively short time. So, I have nothing to complain about. Also, they already lower the fees by 50%, thus asking about company's finance sounds not appropriate.
