It's not a glitch. It's the economy resetting. You can do it over and over again. Even without a bike. Just rob the registers....then walk down the street...stay a second (3 seconds or more) Then come back and repeat. Works with every store and every area. If you get a wanted level, either cheat or just simply use common sense and hide.
Your not understanding what is happening.
Im not sure why it doesnt work for some people but it works for alot of people. You only need to rob the place once, and the money regenerates. You can get about $2000 a minute if you do this.
I dont really care to use this feature, I just happened to discover it while messing around. But I know alot of people are looking for money glitches so I shared
It's not a glitch, it's just exploiting the economy reset. I don't think Rockstar would put those money bags there by accident.
I'm not sure. I don't think R* intended to allow the treasures underwater to respawn either, let alone respawn immediately upon switching back and forth between characters. I can't tell if this and the store robbery exploit OP mentioned are just glitches or minor oversights.
That's just speculation, not fact. The purpose of the game is to chase the almighty dollar. This could be simply a "cheat" or an exploit to gain money faster.
