Well, taking loans from financial institutions will just make it worse because of the interest amount to be paid as well as they set a fixed time within which one has to return the funds, so technically it's a burden on brain which will make trading less effective, while borring from friends and family and promising them that any profit you might make, you will give them a percentage of it, then that will be les burden and I think that's the best way and not taking loans from entities that will haunt you.
For people who are psychologically unstable, it will be a very severe burden to invest using debt. This volatile market condition is enough to make the psychology of investors and traders up and down quickly. Moreover, it is made worse by investing with borrowed money. So the psychological burden is double. But it's not a bad thing either if you can cover it, investing in debt is a cool and brave idea.
