I do not think that Bitcoin will go down under 6000 USD. 6000 USD is the price that costs to mine one Bitcoin and the miners will not sell below this price.
But it is my opinion and it is up to you if you follow it

.
I really agree with you, and we also have to know that the more days bitcoin is getting to know the community. it seems bitcoin is difficult to drop below 6000 $ and it is possible that this bitcoin will increase again in the near future.
