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.
