Do you think it's good to hide real address from surfer?

[Yahook]

I mean hide ref from surfer using javascript onmouseover.

For example link with ref: http://www.paysite.com/?ref=1 and without ref is http://www.paysite.com/

Not at all, especially if you have a content based site. Hiding that means peple can't come back to the exact place they left off.
