I had a friend who took a loan from the company he works for , about 30,000, which would then be deducted from his initial salary.
He then went on to use this money to trade , now psychologically he was just not ready for it because his whole mindset was just about making a huge amount of money that he ended up loosing everything.
Trading with borrowed money is a mistake because there is great pressure that can make traders make wrong decisions because they are too hasty in wanting to get big profits.
It is highly recommended to trade with money that we can afford to lose, because not only profit can we get but also losses because the market can still move against the analysis, it could be because of wrong analysis or other factors that make the market move against it quickly.
And you have to differentiate between trading and investing, your friend trades because he wants to make money quickly because investing takes longer to see the results and agrees that everything must be done without rushing and never go all in.
