i am in this same situation. But i just deposited about 20 bucks worth of btc into my account through the openledger gateway, and it STILL says insufficient funds!? i dont understand how i cant now place a single sell trade. Would anyone be willing to send me a tiny amt of BTS to  . This needs a fix!

okay i just bought BTS using BTC through blocktrades, on the platform. i went to open.BTC/BTS on the exchange and used the blue link "buy BTS".

It would still be preferable to have a workaround somehow.
