As every trader says, trading isn't for everyone so if you are into looking forward to high profits having a lack of knowledge and experience, trading isn't for you. Good for you that you were able to make in other markets as you say, the forex.
This, not for everyone and not for the faint of heart. Because the price can suddenly switch in minutes and majority of crypto traders specially those who are new don't know how to react properly and got burned.
My experience was the same as yours, didn't made that much on my beginning days. Until I've decided to stop it and just focus in holding. I guess you can consider that there's still trading in it but, it only happens when you want to sell at a higher price or buy when the price was a bit low but you have to wait again. So it's a combination of patience and target selling/buying.
I would say that I also have a so-so performance when I was just a newbie trader. Every trade was a nerve nerve wracking to me. Specially thinking that if I did the right move and even withdrawal or deposit back then was causing some stress on me, Lol. But it give me some confidence and experience to continue and ways to look for more profits.
