Heists now require setup fees on the part of the Heist Leader. Not only does this system allow Rockstar to continuously release free DLC updates for GTA Online, but it also allows players to pick what they value more: time, or money? Shark Cards are the microtransaction system implemented in GTA Online, which allows players to purchase in-game funds with real money. Tip: Premium races change every week and are a gamble, as it can take time to fill up a lobby and there is no guarantee you’ll make money.
