One of the biggest mistakes in a bull market is to control emotions. Some people make a logical analysis that they will sell at a certain level, and when they reach that level, they find that all the news in the market is positive and that Bitcoin can reach $150,000 or even $200,000. Then, instead of just making a profit, they wait for those levels until the price correction begins.
Is that not greed?
Yes it's, anyone who has projected some certain price level to sell their bitcoin or any coin and later extended their holdings since news has it all that price could reach 3x by some specific period and they hold back, but instead of price to increase it kept declining.
Then at last they regretted why the price didn't get to that specific level where they thought it would reach happens to be greed, because as a trader or investor who understands the market that are really wanting to take profit would never listing to news instead will focus on their profit making.
Maybe when price declined they can likely apply DCA to refill back their portfolios and wait to target another support level where they would also take another profits with so they keeps making profit from Bitcoin and cryptocurrency except the person has decided to hold for around 4-12 years then there is no need stressing oneself because at some point the price will definitely double.
