It can but I don't think that it will. Breaking an ATH will be a big deal because a top that started a bear market becomes a strong psychological barrier.
I expect a dump if we get close to 20.

Also many people will try to make up for the money they lost in the bear market. They won't care aboout possible future gains if thgey hold past 20 thousand. All they will focus on is to reduce the losses and exit with minimal gain.
