It is very important to avoid greed when trading cryptocurrencies. Whether you are a novice or an old hand, you will unconsciously fall into the vortex of greed. It is human nature.
Since you can't quit, control it strictly. Psychological research has shown that a habit can be formed in 23 days. So it is recommended that in the next 23 days, you only need to grasp two points: first, lock in profits in time, no one can sell at the highest point, and second, don't change positions frequently to chase the rise just because other coins are rising and yours are not moving.
Don't expect to defeat greed, but you can develop a habit.
