I don't know if this one could be fix and maybe they should allow there user to set their own preffered fee so that the user can set according to what they like.
Most gambling sites don't have that feature. And it might become a problem if users can freely set their preferred fees then in the end it will get stuck.
it is the users Problem at least they have given chances to choose which to use right/
Betnomi does not charge the user any fees for withdrawals as per their FAQ.
but i don't think this is the real score , because there are some issues about the withdrawals from their bounty participants recently .
To save fees, only choose coins with less transaction fees. Betnomi has a great number of supported coins with less transaction fees.
Well if they really don't really charge for withdrawals , then there is nothing to talk about these issue about which coin to use for withdrawals .
