If you are having problems getting a funding request to work contact them, and please post back here to let us know how they handle it.
I've got a problem yesterday with a wrong amount because of the fee, which I sent in 2 times to get the correct amount, their answer:
Hello [Myself]
Thank you for being with Bitcoin Trader!
Yes your funding was not credited automatically due to the blockchain fee. Our accounts department is checking all incoming Bitcoins to credit such funds. Your funding has been credited earlier today.
Please let us know if we can be of further assistance.
With best regards,
Bitcoin Trader Support
And I've got credited, no problem so far.
