The panic sellers are those ones who don't want to take the risk for their investment so when the value drops a little bit they suddenly start to panic that their investment won't be reduced to zero so they have nothing in in their hands so they sold at low value to recover to some extent and when the value again rise they also invest so they earn less and spend more so bitcoin are not for those type of peoples if you want to become rich and a good business you must have to take a risk otherwise you will remain own your place or may go down.
