Thanks for the replies!!

Today, I went -10K, and able to finish up +5k

during today's trade session, I had an epiphany that if I get too greedy, I will lose everything so quickly..
Always appreciate what I have, and don't take things granted...

Now I am shorting 100btc at 3920yuan, that was nice move,,
Since I am holding 100btc in my wallet, this will offset any price actions.
It was like an insurance, but paying me off,,  (now it's 3730yuan)


Well I can argue I could have shorted 300btc or something more, but then that's supposing something could have happened
and this will tilt my life and affect my next trading session.  

I am gonna take some rest, BTC will need to consolidate under 3900 level  to go up higher.
4000yuan is just too god damn strong to break it will take few days i guess

Good luck everyone!
