The difference is when we use each one.
Long-term / short-term
We use usually use the present continuous for short-term events - what you are doing now.

We use the present perfect for long-term events.

Example - Reading this book
I am reading this book.
Present Continuous because it is something you are doing now. It started in the past and has not finished.
I have read this book for two weeks.
Present Perfect because it is an ongoing action - not something you are doing now.
Present Continuous for ongoing events

We use the present continuous for when the ongoing event has only happened for a short time.
We use the present perfect when the event is long-term.
