first of all, don't pay attention to those who don't know how to leverage.

if you play in spot you must put 89 dollars a thousandth of $BTC

it is correct to use any range up to 150x, that's what it's for.

What you need to maintain is the margin

if you have 11 dollars, don't play more than 1

1 x 60 is 60 dollars and you can't buy a btc

in this case you must have 22 dollars

Your position in the photo is correct. With 4% you pay buying commission and selling commission and financing

Your problem is another

it's strange but there may be an error in the system. Consult support
