Question about 2x leverage trade and margin

I put 2x leverage on some token at 3.38$ It says my liquidation price is 1.63$. So that means if it goes to 1.63$ my position will be liquidated.

What if it goes to 2$ and goes back to 3.38$,do i still lose something or?

Do i need to pay some fees everyday to keep my position open or it goes directly from that leverage trade?
