Can you margin trade on both sides?

Hi,

So if you put 1 btc for long and 1 btc for short position @ 10x margin. If btc moves against you by %5, you lose 1 btc, but then it goes in favor of the other, and if it goes above 10% that way, you will be in profit no?

Anyone can explain this please?

Also bitmex allows you to change margin afterwards, so can't you start with low margin first and then as btc moves in your favor then, slowly increase the margin?

Is margin amount related to how many contracts can you open?


Thanks in advance.
