I also do not advise beginners to start into trading before mastering the basics, especially since trading cryptocurrencies is very different from trading in other digital assets.
Experience in stocks, commodities or any other speculative market gives you the edge though. With that and with a few months of observing the crypto market, one can become a decent trader here.
On the other hand, there is a good opportunity to learn on some platforms that give new registrants a testing balance with good amounts that enable them to learn before making the first deposit and actually start the process of trading with real money.
Dummy trading can be done on paper too with made up amount of money. I suggest newbies to do dummy trading for at least six months before putting in real money on the line. But may be some less known platforms that do not show bad outcomes to their users, those should be avoided if being done online.
There are channels that offer good advice for beginners, but I do not recommend them either because there are no guarantees that these channels will maintain the same level of integrity.
Dont recommend such channels or groups to anyone, most of them are scamming their users in one way or another. They take the advantage of newbies seeking easy money and use that to rob them with fake promises, fake memberships and signals.
