parasite anchor text

i'm going to try parasite to my new amazon review site. previously i tried medium with generated content and medium difficulty keyword. but it won't work well. so this time i'm going to try with low competitive keyword and unique human written article. my question is which text should i hyperlink to my moneysite? do i need to anchor the targetted keyword? also, is it okay to hyperlink moneysite with 2 or 3 times?

No matter from what pages you link to your site you need to follow the same rules as everyone else.

I recommend you check on of the guides on anchor text. Ahrefs has one, but there are a few others you can find on google.
