What I'm about to describe is the result of years of financial research compressed into simple words, if you want to take a look at the raw data feel free to check the resources below the post.
1st Month. They get a trading app, either Bloomberg's terminal, BlackArrow, or something alike. They play with the safety on (meaning with fake money). They read a lot of news and follow some reputable traders on social media, maybe even buy a course or two.
2nd Month. They decide it's time to get real, they turn the safety off and trade with their real money. If they're lucky, they get some nice little profits this first month, or they drop out sooner.
3rd Month. They get more excited due to the previous month's net positive and decide to buy more courses and start upgrading their daily bets. Unfortunately, they get a net negative this month, but hey, it's part of the game, isn't it?
4th Month. Now they want to recover their losses and start making riskier operations and start losing big time. If they hadn't a safety net before, this is the time the "game" gets too costly to be played on a long-term basis.
