This is not a little negative, it says -3000 something, please take a look at my account.

It is a bug I think. This is what happened: I had 4000 some TGC, I put a sell order (at buying price), it should be executed immediately, but I waited a few mins, it still did not seem executed, so I said ok let me transfer the amount to my wallet, so I did a transfer. After a few minutes, I saw in the notifications that the TGCs was sold, and transfer was rejected because not enough fund (I also never saw it in my wallet). I did not pay attention, and continue to mine. After a few hours, I found my balance becomes -3000 something.

Please check and let me know what happened.
