I bought yesterday for 4.40 each and today price is 3.50... I'm always that lucky

Wait for other listing announcements. Maybe they will stimulate another pump. Or wait for another partnership.
If I were you, I would just wait. Because 4.40 is not all-time-high. As a proof - check DIA graph. Price goes up and down all the time. $3.50 today is not a sentence. Just wait and be patient.
