$SOL The biggest mistake is to enter into futures contracts with a large leverage and burn your money, making it go to waste.
Take this advice from someone experienced in the field and who has tried all types of trading.
At the beginning of 2020, I was the biggest user of futures contracts on several platforms, but once I realized it was a form of usury and gambling and confirmed the matter, I left it for the sake of God. I no longer entered with money that is not mine, and I no longer entered with money from outside the platform. Rather, I made a vow to myself that I would not enter futures contracts with large leverage and burn my money to become one of the doomed.
