Surely Being skeptical to FOMO is a major problem to most people and of course it's not only newbies but to some old investors. I believe the fear of uncertainty that results of selling to quickly (FUD) is base on ignorant and  not having a prerequisites knowledge about bitcoin. Sometimes self doubt and procrastination is a deadly deases that stagnates an investor with such mindset Most times I see such people as gulibles. And they too many but believe me whether gullible or no gullible people bitcoin will do better but we have to change our mindset and follow the right part and avoid being part of the gullible people.
