This is why I don't try leverage because I don't understand it like how it works on Forex where the spread is fixed. But isn't binance going to ask BNB as fees?
There are two types of leverage you can go for on binance
- margin trading
- future trading
But to make it easier, going for future contract is better but margin trading support more coins than future trading.
For margin trading, 3x max for cross-margin while 10x max for isolated margin. If you trade with BNB with margin trading, you will be charged in BNB, if you trade with any coin of your choice, the fee will be deducted with the coin you are trading with.
For future contract, there are two types
- USD-M, which means your trading fund will be in USDT
- COIN-M, you trading fund will be in Bitcoin
Your trading fee will be charged with either one you used to trade, trading fee is deducted from the fund you use to trade.
