I only know that you can minimize the risk if you use propfirm but I am not sure about that. You follow their terms, have a split profit with the company while you have less risk and that could be to those who can't trade well and worry if they will lose money if they trade by themselves.
But if you willing to learn trading and accept the risks while you can manage the risks, I think it is better to trade by a live account because your profit will goes to you fully.
You only need to care with the risks and knowing the decision you should make but maybe I am wrong.
First of all, it's not about minimizing the risks if you are using a propfirm account, because you are not using your own money or account but everything is provided by them, and you only trade with it. Second of all, those who can't trade well and worry that they are going to lose money if they do it on their own, they are also not going to able to do anything with a propfirm, because they will not even be able to pass the test to actually qualify for a real trading account that the firm will give them which will have actual funds and then the profits that the trader makes using that account will be split among them and the firm, but to reach that point, one needs to acquire excellent trading knowledge and skills.
And, even though it's true that one will get to keep all the profits they make if they trade using their own account, we need to understand that you might not have a capital good enough to earn you good profits, and a propfirm will give you an account with a high capital, which means you can make better profits with that, but again, as I sad, you will be tested, and you will need to be a very good trader to actually manage things very well using a propfirm account, otherwise, you will lose the opportunity.
