I suppose that the registration is reserved for German citizens because the site is in German only. If this were the case, the site would be available in several languages. I know that for the English subsidiary (fidorbank.uk) they only accept the citizens from the United Kingdom, so another reason to think that they only accept Germans.
If that is the case, and it appears from their forums that it might be too, then what options work or are available?
Bittrex has recently also come on board with fiat withdrawals but I can't find what their minimum is? Bitfinex is $10,000.....Usually the number required or already above it for the transaction to get flagged and more paperwork/answers needed by your bank...
Since I don't know what you are looking I can't say what options work or not. Are you sure Bitfinex is $10,000? Because using a "
," in English mean ten thousand.
I am using Kraken to withdraw fiat to bank it works perfectly if I make a request before 11.00 am I get it the same day at 7.00pm.
With Bittrex you need to first submit a ticket and ask request your account to be added to the USD markets, then you need to get your bank account approved. So maybe you will see the minimum once your account is eligible?
