1- Are they good or bad?
A- Depends who is hosting them, they could be a waste of time and money; or they could be the best thing you did with the $ of the fees (ICT had a paid group).
2- Are they a scam?
A- Depends who is hosting them.
3- Are paid group leaders so shit at trading that they need an additional source of income?
A- Depends.
There can be an excellent trader who has emotional issues leading to bad trade management. He can use his price reading skills as an additional source of income.

4-Are paid group leaders profitable traders?
A- Most aren’t, some are. ICT is the best trader I have seen and he had one.
Is he a shit trader?
99% of paid services out there are trash used to make a quick buck by the owner, very few are providing value.
