The trading fees for regular contract users in a year
can account for up to 10% of the principal, while
heavy leveraged high-frequency trading fees can exceed 30%++
(large traders' fees can reach hundreds of thousands to millions in a year)
Even for ultra-short-term trading, with 100U 100x
leverage opening and closing 3 times a day, the fees already amount to 30U.
Don't underestimate the operation of rebates, as small amounts can add up!
If you don't participate, the rebates + fees will all go to the exchange.
