No! ofcourse not,,actually it is the best time to produce or buy more bitcoin because that is the sign of bitcoin that it is increasing again remember the 2500$ prediction of 2018? bitcoin hit it earlier, it is just like this one the price of bitcoin will definitely hit 3000$ above in this year and more increase in 2018 for sure.
I observed the bitcoin price whenever it is going to increase. First, it will go down and slowly it will grow. The same thing is happening now. Last night it went up to $2000. I think it may be touched $2k last night. Today again $500 increase in BTC price. See who all bought last night when it went down today they are in $500 profit. Which online business will give you one day $500 profit. So don't panic still wait for some time your profit will increase more this is sure.
