A DC obtained using GetDC() is a so called "window DC" because it draws directly onto a window. You should not select a bitmap into a window DC.
Instead you create a compatible DC. It will be called a "memory DC" after you have selected the bitmap into it because it then draws onto memory.
If your only goal is to obtain a bitmap for use with SetBitmap, BitBlt is not necessary. I got the impression that the bitmap should be drawn onto screen as well.
Nobody cares how it works as long as it works
