Any coin that can bring substantial returns often makes you feel very uncomfortable before it takes off. This is a summary of my multiple experiences.
The coins that truly make people money are usually 'washed out' in this way—by suppressing the market and clearing out those unsteady investors.
This phenomenon of 'washing' is especially obvious during a bull market. Most people start to regret when they see the market rise, feeling like they've missed the opportunity, which is a common trick of the market.
When other coins are rising and yours is not responding, many people will choose to cut their losses and exit. This is the temptation of the market; often, the more you want to cut losses, the more you miss out on the eventual profits.
