I can't blame you for looking some group or community that you think will gonna help you improve your trading. Ive been there, done that. But, I still rely and depend on myself. If you as a newbie wanted to learn, you can follow some of the bitcoin enthusiasts in twitter, joined some tg channels but you should not depend on them and gain more ideas by yourself.

Improvements and success will always be depends on you. How you implicate your learnings and how your mistakes be as your guide to your future success. There's no problem joining to those trading groups but be careful because some are just created the group to pick a victim.
