This is a very normal psychology and nothing strange in life, in any field, there are two emotional state is governed by FEAR and GREED.
Especially in the financial market, not just the crypto market, when prices are rising, people often feel GREED, focusing only on positive trends and never thinking about trends. Negative, when the price goes down, then the person feels FEAR, then focus only on the negative trend and never thought that everything would be positive again.
Talk about this for people to imagine that believing in a current trend is only relative and timed, so look at the market trend with an objective eye (out-of-game) so that If not, then it will not be absorbed in the psychological game of the market. Finance is a game of psychology!
What do you think about this?
Nope i dont believe that only Greed and Fear governed the emotional aspect because theres another one that called DEDICATION and that is what we the true investors having in our lives
Those nervous people that you mentioned are the weakhanded human that enters cryptocurrency without knowledge and learnings on what he was going on
