Demo account :
If you are new, you must try the demo account before starting Trading to build the skills and for a better experience. many trading apps provide demo accounts where you can learn about the behavior of the market in different situations.
If you are new to trading then my only advice is do not invest all your capital initially. Rather start with small money unless yoj have enough knowledge and experience to tackle wild fire of crypto trading against your capital.
Demo accounts is good to gain experience but you get real time experience only when you put your capital on the line. Start with small money once you are done with Demo account.
