You are right. currently, many trading groups only provide information on the assets that can be purchased and forecast growth targets only. even what is given is not necessarily successful.
most such groups share for trading futures on the exchange.
not many provide knowledge and direction regarding the use of the simplest tools and methods of analysis that a beginner can do.
Yes it is true that one cannot gain any knowledge about trading by relying only on crypto signals. I would say that until you learn to analyze yourself, do not invest or trade on the basis of the signals given by any group or any person. I also made such a mistake in the initial stage, not only in the initial stage but also knowingly took such steps in between and I still have to bear the burden of that loss. So I would say to the newbies if you have less knowledge at the beginning of trading, choose all the coins that have less possibility of permanent loss, you can choose Bitcoin at the initial stage for trading.
