When you first create an account, there's a welcome message. Did you bother reading it? It directs you to the wiki (which is also linked at the bottom of every SR page). There's a handy Buyer's Guide: http://dkn255hz262ypmii.onion/wiki/index.php/Buyer%27s_guide Which says, "Your deposit will appear in your account once the Bitcoin network confirms your transfer. This can take up to a few hours or more." Please go read the rest of it, too, it's not that long.
