Do you have any real proof
that the buyout (for all share holders) at 0.55 will not take place ?
No, you haven't !
Therefore I don't think it's very clever to give a general sell recommandation - meaningless if at 0.15 or 0.19.
If you sell at these levels - fine, this is your personal decision, but it's a long way from under 0,2 to 0,55, so everybody should make his own DD & decision concerning Aurus, in my opinion.
