And what is the minimum amount of satosh to withdraw? If there are 30,000 satoshis, and the commission is 16,000, then only 14,000 satoshis will come to the wallet? Right?
30,000 minimum.
Yes, you will receive 14,000 after the commission.
For now, instant withdraws are commanding 39,243 in fees so it's better to opt for the delayed withdrawal (<10,000) which takes between 6 - 24 hours.
30,000 is the minimum to withdraw and the commission is taken on top of this amount. So if 30,000 is withdrawn and the fee is 14,000 then you will lose 44,000 sats from your balance. If the fee was taken from the 30k then you could end up with a negative amount if the fee was above 30k and that wouldn't make any sense.
