LOL seriously? I wonder if anybody else can try and prove this :x
Edit: I think this could be edited too. He could easily stop the video for a minute add the 1B to his pouch, take it out and start the video again?
Yeah it works. It's worked for a while, too. But it is pretty useless because items on the beta worlds are valueless. That's why people drop expensive items and nobody really rushes to look them.
It is kind of fun to do stuff you aren't normally able to do. I think somebody got 99 Construction a real expensive way just because it was like 1m xp/hour and because he wasn't limited with finite cash.
I'm pretty sure Jagex made sure that this isn't going to happen.
And yes there are plenty of dupes on the beta servers, they serve no real purpose though and Jmods don't seem to mind. (They have been asked about duping on the beta before and they just said to submit a bug report about how you did it)
The import cash glitch is pretty useless, I've known about this but haven't even bothered to use it.
Yeah completely useless glitch, I've seen lots of videos about it. For example a guy spent hours duping agility tickets using the same method and got like 200m agility exp for the lols, but obviously pointless.
