How? In minutes? they will recovery in minutes? And why? I'm just want to reduce my losses..
How are we sure that you can profit out of it? You have a -6.5 BTC margin position and you want to borrow money to get out of the hole. Now what if you lose even more, just like the way you lost the first 6.5 BTC?
You can say it's because you have 2.5x leverage and with a 10 BTC loan you'll have 25 BTC that you can trade with in your margin account. Ok, but what if you lose 25 BTC before you make 6.5 BTC?
