why do you think that , the members of POB community keeps selling their POB at a very low price?

Just like what @amr008.pob said, many people are here to get rewarded and sell it immediately, they are not here for the growth of the community, even their engagement was just because of the daily engagement reward from amr and sometimes they keep blabbering just to make it look like they are always actively involved in the community and at the end attract good percentage rewards from @amr008.pob

Most of these people are the newbies that wasn't well guided on how the system works, they were just told to come and comment and earn then sell.. Actually we all like money and its part of the reasons we are here but we shouldn't devalue pob, if the community ain't growing then we will lose also just like its happening already, pob keeps falling everyday and people keep selling

"My people suffer because of lack of knowledge" (hosea 4:6)...

Many doesn't see pob going to the moon in the future and they don't even care, all they are here for is to earn and sell..

The answer to that question, they sell their pob anyhow because they don't care about the growth of the system, they don't even see or believe its gonna develop...
