Or put some of the capital to work from the get-go and trade little by little with what would be left - to train and to test what was previously learned (hopefully).
I agree with your take, it's a good start, but only with good knowledge.
Your suggestion is not bad, but the point is that those who know nothing about trading or are new to it should first read books or articles on technical analysis and at the same time choose a good mentor if possible.
And in the initial stage, the mentor discourages traders from participating in direct trading, but rather asks them to take the help of demo trading. Later, when he understands the reasons for his losses in trading due to which mistakes he can identify and at the same time explain how he achieved profits, only then will he be suitable to use real money in trading.
