Make fill your knowledge first, keep on searching, do some demo, and lastly, start with small capital. It is really hard to start but can be rewarded if you are patient enough and willing to learn.
Beginners needs lots of things need to be done before getting into trading like you have mentioned but I am seeing people are always suggesting these still beginners are not sharing anything like they are good at the beginning days of trading but most of the people are still sharing about their failure in crypto trading.
