It is always better you have a plan over your Bitcoin investment before you invested in it and always try to stick to the plans. Many people get confused because they don't initially have plans for their Bitcoin investment and that is what normally course their panicking whether they should sell or not. Always try to know where you always want to be taking your profit. Asking people to tell you when to sell is not a better idea because nobody is expert in that way, everybody is just saying is own base on their technical analysis views.(knowledge)

Your decision on whether to sell or wait until the price rises even further depends on you. But make an effort to take a seat, reflect, and conduct additional research. No one controls the market price, so it is difficult for anyone to advise whether to sell or not,although it not bull run era but nobody can 90% assure you maybe it will continue maintain the rang of  $20k till bull run time or still fall beyond $15k.many people are only speaking about their own experiences.
