I was once a victim of my emotions when I also started in Bitcoin. There was a time when I converted my Bitcoin into fiat money all because I panicked when reading a certain rumor that Bitcoin will crash. Since then, I realized that I should not be listening to FUDs flying all around and I should never let my emotions lead my decision.
This is my big advice to newbies: Stop. Look. Don't Listen. yes, don't listen to what you read and hear all over the internet about Bitcoin because I am sure that those naysayers are not actually experts on Bitcoin but just want to have some attention unto themselves. Realize that if they are not actually good in predicting things though they might never admit it.
Just hold for more and if there is really a need to encash your Bitcoin then do it for a valid reason!
