If you reached endgame and you need 30 hours of grind to get 30 bil, either you aren't in endgame or you are doing something really wrong. An agris hour at Darkseeker's Retreat, Dehkia 2 Ash Forest, Orzekea or Fortunate Pig Cave if you manage to find it active, should be close to 2.5bil on dry hours and 3bil+ on lucky hours. Doing some semi-afk lifeskill for a couple hours while you are working, or just staying alt tabbed, can bring somewhere close to 800m per hour. There are a handful of cooking recipes that can achieve this number or you can just barter for 2 refreshes per day for 1.2bil. Mercing for guild bosses is another alternative, or you can stack it on top of your semi-afk lifeskills, 30 minutes for 1.2bil in gold bars plus extras. Also, you should have an imperial delivery alt wearing your lifeskill gear when you aren't using it, wearing every lifeskill mastery event buff you can get, that's an easy 300m silver for 10 seconds of your time, 200m if you buy the meals. And then you have fishing as well, what is an average night of Velia Beach fishing? 700m?
If we add up, an unlucky hour of grind and 2 hours of a semi-afk activity, let's say 2 barter refreshes and the imperial daily delivery, we sit at 4bil per day. 4.7bil if you are bothering with fishing. 5.9bil for the days where you also find a guild to merc. As you can imagine, this number can go even higher when you take into account the lucky drops like a BON at the Pig Cave or a Limbo token which may drop once every 7-8 hours. Even if you do half of these and aim for the 4bil per day, that's only 1 hour of active grinding and 2 hours of semi-afk lifeskilling per day, to achieve the 30bil per week.
