Newbies need to start with a demo account, so any platform with a demo account will be fine.
All exchanges are to one degree or another the same in their interface, once you figure out one, you will immediately figure it out in all.
But first, you need a safe environment to practice your skills, and a demo account is exactly what that environment provides.
In addition to learning how to interact with the exchange interface, you will also learn many basic things in trading.
What resources or an application with a demo version can you offer that would visually resemble the Interface of a cryptocurrency exchange? The fact is that I used several applications from the Play Store, but they very weakly visually resemble the exchange and it is difficult to adapt for a person who is still very poorly oriented in trading.
