Haven't had to glitch, earned almost 10mil legit now and pretty much have everything I could possibly want or need, there's really no excuse to glitch other than the fact that you need to cheat on an easy video game.
I find it hard to believe when people say they have earned 5m, 10m etc legitimately. I play 'quite' alot and have got nowhere close to those figures.
Im not saying you have glitched/farmed just that I find it hard to comprehend. If you have, fair play to you.
Some people have different definitions of "a lot" so not sure how much you've played vs people that say that. In all honesty this game is insanely easy to make money in, after 50+ you started getting 18-20/25k missions (obviously different numbers after last patch) practically every phone call, and when you do it with 2-3 other people they go by extremely fast, and with all of you calling in missions you make money really fast.
+ robbing trucks, selling 9k cars, selling simeon cars, races, survival and deathmatches.
This game is really easy to make money in, and if you don't have the time to invest into making all this money within the first month, then don't. I'm not sure why idiots on here try to justify them cheating on a video game they claim to enjoy just because they can't unlock everything in the first month, why do you even need to lol?
