Since joining this thread I have been observing and trying to catch up with some of the regular members of this thread. But I have been thinking of something different. I beg to sway a bit.
I have noticed that the Author of this thread is no longer active but I am glad that members really understand how important this thread is.
Buying bitcoin is an integral part of every investor. Sellers often live to regret in the long run.
Anyone who is new to bitcoin and is asking about if it is time to sell will soon be separated from his bitcoin, and probably going to have fun staying poor, unless and until he learns a lesson to buy and accumulate bitcoin for at least a whole cycle, before even contemplating selling any (beyond spend and replace).
Surely Op had ONLY been in bitcoin for less than 2 years at the time he asked the question about buying or selling, so surely he might not have had figured out the correct answer.
