i just registered with your site and have not made any trades yet.

do you offer stop loss features on positions?  (i dont see it)

how do you hedge the volatility of the value of bitcoin deposits? 

example: i deposit 1 bitcoin at a current value of $200.  how do i maintain $200 worth of purchasing power in my account? 

if bitcoin value drops to $100/btc while i am in a position at 1broker that would significantly affect my margin call ratios, would it not?
