Since the bitcoin technology is very complicated and many don’t fully understand it, they will look for other cues that help them make a decision. One of those cues is to see how many others are invested in a certain project. This need for social proof helps us make daily decisions. But when you are about to put your money in a cryptocurrency, try to look past the herd mentality. Also, we humans tend to put more weight on losses than equal gains. So gaining $10 is not as satisfying as losing $10 is dissatisfying. We are wired to prefer avoiding losses than we are driven to seek gains.
