The futures market is a zero-sum market! The market itself will not create wealth! What he did was the transfer of wealth. And the transfer process is also constantly paying fees! Exchanges and futures companies are places with high wages and incomes, and the money is paid by traders! This is doomed that someone will lose everything! Otherwise, what do futures companies and exchanges eat! 0.9*0.9*0.9*0.9*0.9 is about 0.59.
This shows that even if you are a very cautious person, there is no big loss! Remove the handling fee of 10% every year, and stick to it for five years, and you will lose nearly half of your money! This does not include that you spend six hours watching movies every day and several hours watching related industry news, recovering and summarizing.
