Hello,
Thanks for your feedback. For most coin adapters, you can already set move and withdraw fees.
For the CoinPayments adapter you cannot, however the withdrawal fee is set by the platform to some sane defaults.
A minimum amount for withdrawals is already implied, because whenever you set a withdrawal amount, the withdrawal fees are subtracted from it. If a user is willing to pay the fees, no matter how small their withdrawal is, there will be no cost to your site.
Note that the proportional withdrawal fee that you set in your CoinPayments “Fees” tab is paid *in addition* to the withdrawal fees set by the CoinPayments platform.
kind regards
