This is insane and they will put immense pressure on other exchanges. Also they will lose money when there will be sudden spikes in number of transactions if they will want to proceed withdrawals on time. Not sure if they are aware of that or will be a surprise for latter.
They can also batch transactions to save on fees by for example using a 16 output transaction for multiple users. After BP a significant part of the tx weight on the input side.
Yes I was already corrected. And even without batching there should be apparently max 2 cent fee.
