It's hard often time for people to consider the negatives. That's human nature, and I'm human so I can relate heavily. You become part of a project, you're so excited about it that you don't consider the negatives.
You should not be too impressionable and have high expectations regarding any project.
It is necessary to soberly assess the situation and have escape routes in any scenario. Evaluation of negative aspects is one of the most important parts of your analysis of any project.
As a trader, you always aim to gain profits so you expect that the market price will always keep growing. But being a good and experienced trader knows how to analyse the market and is always open when negative news hit the market which will make the price dump again. It's good to stay positive all the time but sometimes we should be realistic enough particularly in crypto trading.
