I think you could listen to them, but don't blindly follow them. A true investor should not follow other's people opinions, and should just stay with fundamental analysis about the project they are investing in. I won't deny these guys are good, but it's not because they understand crypto, but simply because they are well known, and have millions of followers, so what they say kind of becomes a self fulfilled prophecy.
For the long run, I would say stick to your one analysis. For the short term, these channels could actually be a good option, because there are a lot of guys that just follow them blindly, and if they are a lot, they will move the price a bit and might create a trend (almost like a pump and dump group).
