A lot of cases happens like that, traders are waiting for the dip not knowing that the bounce back will take place, the worse thing is they are quickly judging the market when a small pump take place, believing that it was the bull that creates the pump and in a short span of time they lose their investment following the hypes and bought their coins at the peak. Though by doing your research you can avoid this kind of mistakes, you can enhance your chance by continuing learning the process.
