Bitcoins will never go down to $200 dollars, that is the reason why you should invest even more in order to make more profit in the market while it was still low.
It certainly would not. Every market will always have a stretched point whether we like it or not, and the way the market has been behaving lately showed bitcoin has really reached that stretch point.
We recently saw the way the bears were rejected and then all of a sudden a pretty good bullish rise immediately after and now we are trading above the $6700 resistance with the hope of breaking the $6800, so I would say there could be some good move in coming days.
In my view $200 difference in hours is normal now in the price of bitcoin. In the morning when you see the price it will be $6200 and after some time it will up to $6400 and after some time or at the evening it will again drop $200 to $400. Now this difference in the price is not a big change for investors, but traders can take advantage of this small volatility in the price.
