I haven't. Introducing someone to the crypto market is quite hard if you're going to introduce him with those tools as the start. I think it's always best to go the manual method of telling him how to trade manually before using those tools that have been given to you by that platform. There's tradingview which is a good start to help him with charting. Because if there will be a lot of tools as you've mentioned will be shown to him, I think it will just make things complicate as he's still a beginner.
I certainly agree with you. Suggesting a platform that offers trading tutorials wouldn't be enough. Since you open and shared things about trading with your friend, it would be more helpful to explain the risks as well as the basics and the things that he has to learn because, to be honest, trading is a long process of learning and there are also lots of things to be considered first.
