It has already happened.. Bitcoin went from $19,500 (The all Time High) to less than $9000 during the last few days, do you really think that it was not a correction?
It took more than 20 days to have that correction done, but it took place.
So no, for me, that correction is over now and the price will go up during the next few days (with no exception)
So let's wait to see how does it goes.
