I heard to use the option "post only". But I am not an advanced leverage trader so i would be very thankful for some insights and tips.
If i go with the option isolated then in the case of liquidation only my initial margin will be lost right?
Isolation trading means you will not be able to transfer any other funds into your active future trading. So, if the price of the coin get to the liquidation price, you have no option than for the fund to be liquidated.
The other is cross margin, in this case you will be able to send more funds invade you fund is about to be liquidated, you you transfer more find into your future account, the liquidation price will be reduced. Example is assuming you have $40 in future account, you go long (buy) bitcoin and leverage it 3x, bitcoin liquidation price can be $15000, but if you transfer more bitcoin to your future account, the liquidation price will reduce less than $10000. It can reduce to $5000 depending on the amount you transferred into your future account during cross margin trading.
