Hi
I used to short at bitfinex and have some idea how to short BTC but I had to close the account at bitfinex for some reason
Now I tried shorting at binance but unlike bitfinix I actually had to "Borrow" funds at a cost despite I have sufficient USDT in wallet.
Am I going in right direction or is there any other way to short without actually taking borrow.
I believe you do margin trading instead of of future trading since you mention you are just borrowing it. I'm using binance exchange for futures trading and I'm sure that you used margin trading. If you are using binance mobile wallet. Futures was located on the bottom part which is fixed position, It is between the wallet and trades function.
Refer in the image below for more precise location.
