Is the bottom in or can i still sell? 
You can sell any time that you like. It depends upon how apportioned you are. If you are 100% BTC, then maybe you should sell a bit. If you are only 1% BTC, then maybe it is a decent time to buy some, and figure out a longer term plan rather than asking on the interwebs about what to do about your personal bitcoin allocation situation.
I have 30 btc to play with and some more in cold storage which i wont touch for a long time.
I dont plan to invest more, but rather want to increase my stash with trading. So far this year was quite good with me (us).

Resistance to me, 2017 breaks in the process we are entering in a few months if I stay above $ 1000 will fall again afterwards. Even the Chinese stock exchanges are rolling in turbulence at this moment, and I hope that this dump will continue to rise in the near future.
