I periodically watch the YouTube channel "Retire at 35". The author of this YouTube channel is a very talented marketer and evangelist of the FIRE strategy.
He made a lot of money helping various commercial companies increase their revenue. For his work, he asked for a certain percentage of the revenue received. This strategy helped him accumulate a large amount of money and start investing. He realized his dream - he retired at 35.
The author of the channel "Retire at 35" likes to repeat that capital is earned not on the stock market, but in other places. The stock (cryptocurrency) market is a financial instrument for saving, not for making money.
Youtubers don’t make their money from trading or investing. They make money from views. So I automatically diss channels like the one you mentioned. Of course every once in a while they may come up with good info but you could find that info in pretty much in any entry level finance book which explains what FIRE is.
The one I like a lot is:
“Rich dad poor dad” from R. Kiyosaki for example. I gives you a great headstart.
