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.
Everyone has it's own insider information, the question is whether it's true or not. And with that advent of online specially in the last five years, many of us have heard one information or another and then we treat it as somewhat someone from the inside. Nevertheless, it could come from anyone to be honest and then they can spit it like some kind of information they got from a reliable source.
It's more evident though in crypto space or some memecoins that just got out, and then word of mouth, spread like a wildfire and then the pump and dump. That's why it's very easy to manipulate their price and make money out of those who blindly trust those so called "insider information".
