Dangerous point of credit happens more than once (6)
I believe the answer is:
crisis
'dangerous point' is the definition.
'crisis' can be an answer for 'point' (I have seen 'Crucial point' mean 'crisis' so perhaps 'point' could also mean 'crisis'). I'm not sure about the 'dangerous' bit.
'credit happens more than once' is the wordplay.
'credit' becomes 'cr'.
'happens' becomes 'is' (to be can mean to happen).
'more than once' indicates the doubling of some letters.
'is' duplicated is 'isis'.
'cr'+'isis'='CRISIS'
'of' is the link.
Can you help me to learn more?
(Other definitions for crisis that I've seen before include "Emergency - decision time" , "Crucial and dangerous moment" , "unstable period" , "Climax point in, say, a fever" , "Crucial or decisive moment" .)
