Almost everyone who enters the cryptocurrency circle is fooled into doing contracts, thinking that contracts can earn more. If you can earn 10 times as much as spot trading, you can earn 100 times as much as contracts.
However, if you can clearly understand the market and layout valuable currencies, you can earn 10 times as much as spot trading. In theory, you can earn 100 times as much as contracts, but if the market fluctuates randomly, your position will be blown up. You can’t earn 10 times as much as you could have, and even lose your principal.
