My BTC balance was reduced on 58% now by poloniex. Is it normal?
You may have forgotten about the BTC you had in trade orders. I had one order cancelled to reduce my negative balance.
No. I requested to withdraw all BTC before bad news were. I know how many BTC I requested (it can be checked in confirmation email).
This request was canceled and now I have only 42% of my yesterday BTC balance.
Why did poloniex take 58% of my money?
