There may be a number of reasons why you are unable to withdraw your Euro or US Dollar:
No, or insufficient balance in that currency
Is your current currency balance sufficient for your withdrawal? It is not possible to withdraw a higher amount than your current balance minus applicable withdrawal costs.
Please note that you can't withdraw a Euro and US Dollar balance as one amount in for example Euro. You have to withdraw any balance separately for each currency you hold.
Limits apply to fiat withdrawals
Did you try to withdraw a higher amount than your daily withdraw limit, or did you already do other withdrawals over the past 24 hours or over the past month? You can find the limits that apply to fiat withdrawals here.
It is only possible to withdraw Euro or US Dollar if you have a Tier 3 account.
Fiat balance blocked by open orders
If your account has open orders, part of your fiat balance may be blocked by these orders. For example if you have an open Limit order to buy 1 Ether with 200 Euro, the amount of 200 Euro can not be withdrawn from your Euro balance at Bullex. If you want to withdraw this euro amount anyway, please cancel the open order to free up your balance.
