I agree going on with small amounts first. This is lessening the risk that you're taking upon trading and newbies don't have to jump to big amounts as they start. That is one common mistake that we see being done by them. They jump to the conclusion that they'll earn big if they start big but no.
I used to practice this when I first got to know trading because knowledge about trading was not good so it would be better for people to learn first and continue trading with much smaller amounts. It's about how to handle risks so as not to get trapped in a much more serious psychological situation. Starting with a large amount will not necessarily produce large profits, especially if beginners do not understand how to trade properly.
So, take some ideas from the signals but still study them and analyze if they're good or not. Well, it's up to you if that's what you think with signals and they're meaning ful.
For me, it's just best to avoid any of them because you might be one of those that are being manipulated by these signals instead of you being aware of them that you should them.
As long as we try to analyze it is not a problem because for me following several signals can increase our trading skills. A person must have complete knowledge so that the signals they get from other people can be verified and in this way people will become more mature in trading. Without us realizing it, there are many people who make tutorials about trading on social media and perhaps without knowledge it will be quite difficult for us to verify the level of accuracy.
Everyone has their own views on this and I'm sure those who are experienced in trading will know what to do. Especially for beginners, they may have to learn steps like those discussed above first so they don't get trapped in the wrong trading system.
