This is my first post so hopefully this is in the right spot.  I have a question about trading bitcoin with leverage on exchange.  My questions: 
I did a test position...bought in when bitcoin was 10k sold at 10,700 with 2x leverage...only got back 10 or 11% profit after i closed my position....i understand i was not going to get entire 14%, but they kept about half my profits (i would have gotten 7% with no leverage).... Is this normal?
