At the end of the contract, it will go to zero. Most people incur more losses than gains.

Do not trade contracts, especially for those who are in debt and using credit cards for borrowing; they should avoid contracts entirely, as the probability of liquidation is 99.99% and the probability of profit is 0.01%. If you think you are part of that 0.01% who make a profit, then you don't need to trade contracts; just go buy a lottery ticket to achieve wealth faster! One should have self-awareness and not be blindly arrogant! Also, do not believe in those so-called masters or expert traders, unless the money you are playing with will not burden you and you can afford to lose it!
