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
We must not expect everyone to buy into our idea or have the same opinion as us. I believe there are members who will discourage you from partaking in trading as a newbie, and there are also some that will ask you to start. These are people with different opinions, and they have their own reasons for saying whatever they say.
Anyone who advises any newbie not to go into bitcoin trading is just looking at the risk perspective and advising the person to play it safe and don't endorse such risk as the newbie might not yet be ready for such.
Those advising you to start where ever you can also mean well for the newbie as anyone can learn from anywhere and we don't just know one thing without starting from scratch, so taking a few lessons, maybe start from a demo account for trading, do some reading and reacher, then make your conclusions and start from somewhere. Everyone has their own beliefs and career to chase, so mere words from members can't kill that dream for anyone who is determined.
I don't question others judgements. I just give advice based on what I think is right for me to do, and every other person can do the same thing. It's now left for the person in question who wants to engage in trading to choose what's right for him.
