Because the thread was established at the moment of momentary euphoria. When the price rises for a few days or weeks, many people (usually new speculators) don't even think about the price can start falling. Unfortunately, it is never the case that the price will always only rise. At the moment we are in a trend of very strong price drops and I think that the price will continue to go down. It is possible that by the end of March we will see even $5k.
