Can I deposit BTC and trade? If I do, will a part of those BTCs be eaten too?
Bump. I want to know this too.
If I deposit 1BTC, will I get 1BTC in my Poloniex account or will Poloniex deduct 12% from the 1BTC?
If you have to ask that question why are you even considering sending funds to that exchange?
For me, if I had to question the outcome of my deposit on to an exchange I would not be using them. Period.
