If you play contracts, you must have a rebate, otherwise you will suffer a lot. I will do the math for you, for example, if you use 200u to open 50 times, that is, you have 10,000u, according to the average handling fee of 4 per 10,000, the handling fee for opening an order is 4u, and the handling fee for closing an order is 4u. This is 8u for a contract that has not been done. Don't underestimate this little money. If you open a few orders a day or even open orders frequently for short-term trading, this is a considerable fee. If there is a rebate, these fees can be returned to you half. If you play contracts frequently, it is also a considerable fee.

In addition, everyone must play on Binance, and you can rest assured about your assets. Don't go to unknown exchanges. #BTC
