Gain a bit of a following (3)
I believe the answer is:
win
'gain' is the definition.
(I know that win is a type of financial gain)
'a bit of a following' is the wordplay.
'a bit of' says the answer is hidden in the clue.
'WIN' can be found hidden inside 'following'.
(Other definitions for win that I've seen before include "Trumph" , "Be victorious or succeed" , "Come out on top" , "Be successful" , "Achieve victory" .)
