So, if you want to invest, it's better to use your own money. If you don't have enough money right now, there are options for saving, although that takes time. Better to be late, than to curse borrowed money.
You are right, it is always good to have your own money and not borrowed for an investment, because you always have to think about the case that everything goes wrong, and the investment is lost, in this case you must have how you can respond to any eventuality, unless If you have privileged information about a project or investment currency that is highly possible to occur, if this is the case, then the risk is welcome, but it is seldom certain that a certain event will occur as planned, it is all a risk, and in crypto anything can happen.
