Yeah, I understand your pain. I have seen someone here in this forum discouraging someone from trading. It's really bad but you wouldn't give up either way. Don't let others define you. First what you do is find the basic places you could learn about trading ( some exchanges offer such knowledge) then you can read books and maybe try copy trading if you want
When someone has that motivation of doing something that he loves and you discourage that person I don't think it would be easy to convince him or her to go back to that idea ever again.
The best is never to speak ill about that person's intentions or rather you use supportive words to lift that person up no matter how long it takes before learning and be good at it, is worth it I'll tell you for free.
If someone is ready to trade just encourage and support whosoever that person is rather than killing the person's dream of becoming a better trader.
Yes, because if you really want to pursue what you want, whatever anyone say, you will still do it and prove that you can do it.
I see some high rank that gives advice to few newbies asks egarding trading. For me, they are not speaking ill, newbies should never treat it as a discouragement. You see, they have their experience and advising what the newbies need to do first. It is not about stopping but to get more knowledge before doing trading.
