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.
Yes 20K is actually very cheap these days. I use alot of Bitcoin Services and most places charge at least 40K+ sats. And most of the time when you actually look at the withdraw transaction, its pretty close to the amount that was charged for the withdraw fee.
A manual tx fee is not always a good idea. I think Bitmex is one exchange that lets you set your own withdraw fee and its great however you need to becareful. Reason why is because you have no idea how many inputs your transaction will have. It can have 1 input so it will have a higher sat/byte fee or it can have many inputs and your transcation will have a very low sat/byte fee and might not get confirmed until the slow weekend sometime. Hence why its always better to pay a higher fee than a lower fee.
