You literally can't do any personal analysis when it comes to fomo because you'll miss the opportunity. It gives you least time in order to see if the crowd is already buying it more and more or not. But the thing is, setting up a limit buy order or jumping in quickly are the major factors playing an important role here. Even if you hold patience and set up a limit buy, chances are you may get it filled with an immediate dump and see a good rise again while making some extra percentages rather than buying it quickly at its peak as you'll lose greatly in the end. Never go all in during fomo.
