Guys may be selling because they need the cash for other things. Like buying meds for their kids or getting their cars repaired. Lottsa reasons for selling bro.
OK, second reason. Maybe they are of the bird in the hand persuasion. If they bought on June 15 for $0.0006, they have a 1900 % profit aujour'hui. Being Christians, they are happy with that leaving the big bucks for others. Gawd bless 'em for their lack of the green eyed monster - greed.
