Holding an avaricious attitude (8)
I believe the answer is:
grasping
This clue is a double definition.
'holding' is the first definition.
(grasping is a kind of holding)
'an avaricious attitude' is the second definition.
(I've seen this before)
(Other definitions for grasping that I've seen before include "Miserly; seizing" , "Greedy, avaricious" , "Acquisitive - understanding" , "Holding" , "Gangs rip, being greedy" .)
