Those who sell when they make a small profit are not investors, they are short-term traders. If you want to invest in Bitcoin, you must have such a mentality that my invested money will last for a few years or centuries and I will survive here until the end. Basically, Bitcoin is for those who are patient, not for those who are in a hurry.
Bitcoin investment isn't something that needs to be rushed although there are tons of person who have even gotten the idea of bitcoin through the perception of bitcoin being something thats very easy to make quick funds from which is entirely not the case as with bitcoin investment you will have to sacrifice alot to keep your investment standing strong if not you are gone. But the fact still remains that not everyone is willing to have the mindset of playing the patience.
Patience and controlling greed are the most important factors in Bitcoin investment, the person who can control all these factors will definitely be successful in Bitcoin investment. Many people invest but they do not know some strategies, in the end, they have to sell their Bitcoin holdings due to scarcity. Whenever you invest, you cannot have any thoughts of selling your investment immediately, you must have a plan, you have to be patient until you reach your destination according to the plan.
You may have to have a plan for the amount of patience (2 bull markets and about 8-10 years). Then you will get the most success in Bitcoin investment, more Bitcoin investment should be held than this, it usually depends on the person holding Bitcoin.
