You see, for the past few days I've being trying out some of "crypto prediction apps" but I haven't been lucky. It would be enlightening to know the percentage of other traders who use prediction apps.
You have already mentioned the reason why you shouldn't follow this crap. Obviously, even a professional trader is having a hard time predicting the market so what algorithm does this prediction app is following?
It's the same as following a certain signal group. It's only for reference purposes but not that you will actually follow it.
If you want to be involved in a trading discussion group, I suggest joining the Binance Telegram group
(https://www.binance.com/en/community) either on their general group or if there's an available group for your locals. There are
"real-traders" lurking there and you might have a good read on their discussions.
