DYOR. Don't blindly follow signals given by some other "gurus" or bots. Educate yourself to read charts and only through learning and failures you can master trading.
Definitely, that's right because crypto has so many elements of surprise. We really never know what will happen to a coin because no one really control its price. Better to be a dependent because trading can be learned through experience and there are a lot of resources that we can actually make as a reference to be able to learned some skills about trading. Well, following signals can be a help but if you're wise enough that you already learned some of their skills then maybe that is the time to leave and continue based on what you learned from them.
