This company has only 40million shares ..that is not many..so i personally doubt theories on" capping stocks"as it would require some mm's.GO ahead and bid  $2.00 a share ,you will get them lol.Of course we wouldnt bid that but you get the point,lol.There is high hopes for zen in the near term so noone wants to sell their shares but at the same time noone wants to pay too much over the ask ...normal activity as i see it....with a lot of crossed fingers glta
