In any case though, for average joe like the majority of us, this option is not viable, or at least joining a trading signal groups is not recommended because we all know how this fraudulent groups operates and mostly the admin or the people behind as the ones going to profit.
I think you are on the wrong path here. I bet everything I have that crypto is full of insider trading, like explosively full of insider trading. No reporting requirements to the public like ad hoc, nothing even remotely close to the stock market where insider trading happens all the time despite regulation. There are studies that show suspicious share price movement minutes before a public report comes out. That is called insider trading. In crypto it is so easy to do and it is done!
