Maybe I'm quite impressed by the saying, you will never know if you don't try. Learning forex with the internet makes it easier to access various information, including about forex trading. Anyone can learn forex for free by reading forex articles, forex ebooks, YouTube videos, and so on.
However, I also see that there are traders who like to learn forex through seminars or from mentors, even though they have to spend money, which means it's not free. Maybe their mindset says paid-to-learn gives better results than free ones.
Back to each trader I think, if you have enough funds to learn forex trading, please look for a mentor who is truly a trading expert. However, if you want to learn for free, you can use a demo account to practice and learn trading.
