first of all, don't make your site public on this forum. Especially an Adsense website.
secondly, do NOT share your Adsense site with your friends and family cause you risk losing your Adsense account (it's happened to one of my friends many years ago when the guy has shown his website to his family and his mother had started clicking on ads many times a day to "help" his son earn more, and he had lost his Adsense account). If you care about your Adsense account it's better not to share your Adsense sites with anyone, take my word for it!
thirdly, Adsense pays net 30 indeed... well, it used to pay like that in 2014 when I last did Adsense.
regarding withdrawal buttons.... if you've chosen Western Union as payment method (that's what I used back in the day) you won't see a withdrawal until the day you are sent the money.... or at all (I don't remember how it worked). For other withdrawal methods I can't say because I never used them, but if I were to guess I'd say that you also won't see a button until the day you need to get paid, so don't stress about it. Your main concern should be to get traffic to your site so you can generate clicks and revenue
