I don't believe most traders are not profitable, trading has been one of the alleviation scheme from poverty to a lot of intellectually smart youths, as for the newbies in trading they might experience loss but its just a matter of time and also they can utilize the copy trading features on some exchanges just like Bitget, the copy trading will give them opportunity to make profit by copying trades from professional traders.
Most of trader are failing, its only very few that make it, those young trading gurus selling course over youtube out there or tiktoks are making money from affiliates and course, they're not purely making money out of trading, pretty sure if they can show their trades its gonna be mediocre, not even worth mentioning but many of them just go and sell courses because thats the best way to make money risk free without spending any capital just creating some bullshit guide to how to make millions of dollar even though the creator doesn't make their millions of dollar from trading.
its overall just useless knowledge being sold at high price.
on the other hand anyone better off doing themselves favour and put their idea into action with that money, on the other hand copy trading might seem promising, but sometimes buying position just to copy the pro trader and their existing position on certain investment isn't really great. they probably got the position on significantly lower price point than when you try to copy their trades, also, some platform allows for copy future buys, doesn't mean you gonna profit though, it still depends.
