yes, before when I was still studying crypto and I still knew little about it, I would pay for a signal just to double my capital and what I paid for was a coach who would teach me strategy in crypto
then did you able to make double? signal is worthless i think, if paid signals working and everyone can profit easily then no one lose here.
i did not believe it from the beginning of my trading, i heard some people profit here but end of the day they leave from with big loses.
I would like you to put a condition that "most" external signals are bad so that you do not entirely discourage people. One thing I have learned on the social media space is that people have weak and shallow minds and whatever they read first might stick in them for so long, if not forever. This is why I always like to refine what I write so that I will not be generalizing things just like most people on BTT do.
As for the subject matter, I like to say that some external signals are good, but you must first locate the best ones that will be good for you. Is it daily signals, commentaries or a signal-providing system, yes, you can actually find the right ones that will ever be helping you to gain money from the market. But this might be painstakingly done for it to work for you, not that you just make some few searches and you get tired or contented with the ones you've seen. It takes time and regular searching, this was what I did then and it could take years at times. What also helped me was the forums I joined, seminars/webinars I attended and some broker's newsletters. With them, I was able to discover some in-depth trading sites and tutors. There were also links that were shared as well that were informative.
You might also want to take this route like me, maybe you can have a change of mind on this.
