50% correction isn't a correction but a price crash which I think is possible but not in a short span of time and i believe it is not happening anytime soon. It might happen when the dominance of the Bitcoin market started to fall.
I mean correction and drops are actually healthy in the bitcoin market and just like what happened with the continuous pump of bitcoin up to 40k$ obviously people are expecting a correction already.
Indeed correction brings a window of opportunity to the investors to join the market and it enables people who sold to rebuy and join the market again.
