I will listen to their advice calmly but i will decide sell btc following my feeling , if I feel the price has reached my target then I will sell few of them to secure profits.
That's the right thing to do, listen to everyone but only follow your gut feelings and sometimes the expert advise can even go in our favor and if you feel that you are making enough profits then you can sell your coins.
I agree that it is one of the best decision a person can do. Listen then study the scenario. At the end of the day you are the one to decide so it is a good thing not to have an argument with them. This will not only showing them your respect, it will also save you from a heated debate that may affect your relationship with them.
Yup and even if we take decision as per their advice and if it proves to be unprofitable then we should not blame them as it was your own decision and you should be always ready for the worst.
