Yes agree, patience is the key. If not impatient, then we will tend to panic. Seeing the price drop, people who are impatient (quickly panic) tend to be quick to sell it for fear of big loss. Likewise when prices rise, impatient people will tend to sell them quickly.
If you will be impatient here and be greedy crpyotcurrency is not for you. That's for those people with that attitude I suggest leave crypto now or else you will lose all of your money here unexpectedly. But if you will be patient and can overcome your greed you will be rich here.
