Well people do always says to hold bitcoins. But for me it would take you to a very long process. This maybe the safest way? Maybe yes or who knows. Some do trading pro traders actaully gaining profit and i think it is enough yet much risky than just holding
all will not tell the truth whether he holds for a long time or choose to do active trading as well as you because you have your point view.
I think we should not listen to others, as its our own money we can do anything we want, if selling is the best option then we should sell it without any hesitation.
Right people decides because they are afraid because of course of the risk. But in life we should really have to take rest. If you fail then its ok grow but if not then you succeed
