Nope, never listen to that because of them are fake too and maybe get paid by some people to do that.
It's only in cryptocurrency but technical analysis in real world real market, i'll listen to it. I always think technical analysis on crypto is not 100% true.
If the technical analysis is made by someone else, then you should not fully believe it. you're right, they provide analysis of course with their own interests, so don't easily believe their speculations and predictions. do analysis with your own skills more better..
