This is really important.
Use your own money. If you don't have it then don't start at all
I think this is not really necessary, no one decides to engage on the exchange if they don't have any money. And nobody thinks about becoming a trader if they have no economic ability (money). Basically, only people with money think about investing in other things, maybe someone will think of margin mechanism on exchanges, but to be able, they need initial capital.
I doubt that, there were still some few people who wanted to become successful by becoming a crypto trader, they started with just limited amount of money, they are those people who were not contented with their life anymore and they wanted to change something, and I've known a lot of people who has nothing and now has everything.
