In Binance Future Coin-M

If I have 1 BTC, equal to100k USD.
I put it in COIN-M wallet
and I open long position 2x, with size 1 BTC, margin 0.5 at price 100k, Liquid Price about 50k.

Suppose I pay .01 funding fee for 1 month.

After the month
If the price of BTC go to 110k.
I close position.

Question: how much money I will have?
(BTC and USD)

Can someone explain me how to calculate fee in Binance Future coin, BTCUSD CM

what Cont Size, Magin BTC means
and how to exactly calculate funding fee
and amount gain when price increase

Basically, I want to leverage BTC only for about 2x.
I have option either use Margin, borrow Usdt to buy BTC, assuming interest about 20% a year.

Another option is to use my BTC to buy BTC future, funding fee .01% / 8H. Using leverage either 1x or 2x. Whatever keep liquidation at 50% of current price.
I'm not sure whwther this funding .01 is about .01*3*365 ~ 10.95% on BTC or not. or it need to multiply by cont size, or else.

my target is 2x, and keep liquidation level at about -50%.
Goal is choosing the one with lower fee to lower risk if price doesnt go up.

which one is better option?
