people just rubberband their controller and leave their console on overnight. you get like 3 levels, $250 and half a gold bar in that time. it's insane.
It's like there are so many things in here purposefully designed to annoy the player as much as possible just to nudge them to use shortcuts (a.k.a. MTX) to ease that experience, haha. This is my first Rockstar online experience (aside from like, half an hour in GTA Online) so I am actually rather surprised about all these aspects.
