I do not find any information about withdrawal fees and limits for the different coins at your site. Do you take any withdrawal fee for BTC and what is the minimum limit? If the information about fees and limits is written anywhere please provide a link, thanks.
If logged in, you can see the details for the coins you specifically have a balance for, here;
https://hashco.ws/balances/I suppose it may make sense to also add this information to this link;
https://hashco.ws/usercoins/ which shows all the coins regardless of balance. I'll add it to my list.
