I'd be truly amazed if 1-5% of the people on here who claimed they were becoming full time traders had anything more than a pot to piss in after a handful of months. Those who are on here boasting about their prowess are likely posting from a public library before going back to their sewer for the night.
The average human simply does not have the wiring to make a success of it. At least shitposting doesn't require risk management or analysis.
This. There are just SO much self-proclaimed expert/professional traders out there, just because they got lucky with a couple of trades by buying in on r/cryptocurrency hyped coins or listening to those pump groups. People are definitely oversimplifying and heavily underestimating the difficulty of trading is.
