Recently, my friend asked me to advise him on platforms that would help newbies to the crypto to start trading and not go at a loss. I haven't worked with such tools and this question baffled me.
Do you mean trading platform or kind of trading bot?
So far as I know, trading platform will not guarantee their users not to lose. Because, the loss or even profits are managed by the users itself. They will not be responsible of any loss that users will probably get. It is because trading platform is only a platform or exchange that provide services for buying and selling cryptocurrency. And sometimes there are also additional features like what Binance and other exchanges have. But no guarantee for the loss.
If you mean it is about trading bot that will help him to always take profits without loss, seriously?
Moreover if that is a free trading bot, this will never guarantee him not to lose. I think that it is better not to suggest him about certain platform because it will be too risky for you and he may blame you if he loses someday.
