Noticing that many people choose to trade contracts with loans, I must remind everyone that this practice should be approached with extreme caution. Playing with loans could put you in unpredictable situations, ultimately leading to heavy debts. I previously saw a friend who shorted Bitcoin with hundreds of thousands in loans, and now he only has ten thousand left, having to painfully cut losses. This isn't the first time he's stubbornly endured losses without learning a lesson or setting stop-losses. Investments should be made using idle funds; using high-interest loans for investment is akin to killing the chicken to get the eggs. We should not harbor fantasies of getting rich quickly; it’s better to take it slow, operate at lower leverage. Although making money may be slow, it is at least better than facing liquidation. Being able to control one’s desires already surpasses many others. Proper position management, setting take-profit and stop-loss points, and carefully observing market dynamics are essential; trading should not be treated as gambling.
