As we can see through all this months bitcoin cannot break 6800$ point. But the day it will happen I do not see any special reasons to affect on mining, because of even 20000 $ point didn't make anything special with that area of crypto business.
How many months have you seen bitcoin breaking the $6800 point? 
That was just recently and the only thing we have tested severally now for a very long time is the $5800 - $6000 support which I believe even though has been holding does not mean we still cannot get the possibility of it being driven down hard if it breaks lower. Being in a dangerous area is more like saying we are in an indecisive area with the market trying to find a direction and at this point, it is always risky trading the market without some tight stop loss as the case may be.it all depends on the way each individual may want to look at it, but for someone going long, they can always decide to go in at any point.
Yes, these dangerous zones are only for short term players and as you just mentioned I never worry about the bitcoin's current range bounded trading. I hope it will break these dangerous price area and will go up. It is October and we may expect something new from now onward.
