This is the usual movement of bitcoin, every time it dip very low it will sure gain the amount it went down and even went beyond that recent All Time High, And you are right to not panic so it can be a straight forward increase for the value of bitcoin,
For the past 2 years, yes that was the right trading strategy to use. Now, I do not believe so. There has been lower highs and lower lows for the last month and it is anyone's guess on how long that might last.
But Speculating the movement of increase for bitcoin is in the month of February so be patient and have faith in it.
That is the kind of thinking that most of us are stuck in the "denial stage", while the smarter traders are starting to either take the opportunity to trade to fiat to buy low or to short Bitcoin.
