Maybe the OP just created this thread with the aim of earning merit, but since he was not able to earn merit through this thread, that could be the reason why he stopped being active in this thread.
Have you taken the time to read the OP again? I don't think he created the thread to earn merit, and my reasons are; 1. If it is about the merit attraction, he would have made the heading only "Buy Buy Buy" and not added the "Sell Sell Sell" because that's the sentiment on the forum.
2. The body of the thread is too short, while the remaining part is questions and wasn't constructed well enough to attract deserving merits.
I agree with you, if someone should carefully go through the OP thread over and over again you will find out the OP intension is very far from earning merit from the thread but i wonder why some people are saying that the OP created this thread to earn merit perhaps even if merit was among the reason for this thread then i think it will be the last thing or the least of his or her reason or thought. However, this thread is simple and obvious that the OP was just trying to find out if the period he or she created this... is/was the right time to sell or buy coin because of what he or she has been hearing or perhaps witness people do and whatever the reasons are i do not care as far as it has helped shaped and make me understand things i do not know before, i think i am happy and at same time grateful.
