I have joined 2 discord group of crypto traders led by @Mindset_BTC and @bloodgoodBTC -- that's their Twitter handle. You can chat or ask questions from there but it isn't a community that's frequently active who will gave signals for you to follow. They also have trading resources just to get your feet wet.

Or...you can just hop in to the Speculation[1] or Trading Discussion[2] board here in this forum.
