I wouldn't follow anyone giving trading signals. What happens if they make you good money and then all of a sudden they stop posting their trades? What will you do then?
Best to learn trading by yourself.
I would never follow other analysts
blindly. That's a given, and it's why most paid signal groups are garbage.
However, it's invaluable to pay attention to other analysis than just your own. It's easy to become biased and get tunnel vision otherwise. I follow a dozen or so traders on various mediums, both privately and publicly. I also have a couple trading buddies who I chat with almost everyday about BTC price action, market data, and so on. Not only does this help me "keep my nose clean" as a technician but it also provides me a glimpse of what the rest of the market is doing.
It takes years to become mechanical about proper trading rules, capital management, defeating analytical biases, etc. Until you get to that point, surrounding yourself with competent traders who have already been doing it for years is the next best thing.
