i really laughed when i found out that there are still many people who are willing to spend hundreds or even thousands of dollars just to join a trading seminar even though the knowledge shared there can be obtained easily on the internet today or directly by meeting a trusted personal mentor. Learning autodidactically on YouTube is very good, but it's even better and more effective if you learn directly from a trusted mentor, who already has experience and a good reputation in trading.
indeed its such a silly way to waste money meanwhile they could easily use that money to start trading on their own ignoring all of these useless course which material actually just coming from curated free material out of youtube and then remaking it.
if a newbie wanna learn the basics of trading its better if they can head out to the exchange that they trust usually they have some basic material for learning trading and investing that they could get for free since you are potential customer of that exchange usually their trading material is top notch no need to pay unnecessary fee, use that money to start trading as soon as possible to know the ins and outs of trading and investing. by doing that you already doing yourself a favour to speed up the process of learning.
therefore its simple really, even binance is having their own specialized resource exactly for this called binance academy.
