Insider info is not that difficult to get and financial markets have become easier then ever before to make money.
A lot people use just insider info to make money there is not really analytics but even with the lowest IQ and without any degrees or education at all you can just make money If you got insider info and many even uneducated without any education at all doing that.
Doesn't it take intelligence to find an insider? Because you might actually meet a fraudster, not an insider, so intelligence is needed in all aspects so that you are not easily fooled, also trusting an insider without doing further research is a mistake, so your statement is wrong, if read by lazy people it will be considered as justification for their laziness because they assume that insiders will make them get money without hard work.
