I will no longer tolerate post saying this is not possible. It will be classed as spam. I have given enough information already.
Does that mean that you can lie and tell people that they can't say you're lying? Go tell a mod. I've been banned once for telling the truth; the person who lobbied to have me banned is now banned himself because----wowies!!!----I was right in the first place. If I get banned again, oh well again.
There's no way to make 3 billion a week on a Runescape 2 server with the balanced trade rules in place. A really strong player would have to be lucky to make 1 billion in a given week. 3 Billion a week is possible on Runescape Classic, but it would take some preparation. It probably couldn't be done every week, and especially not with the limited number of players today.
Without getting into detailed statistical models to prove that it's not possible (I'll bet you kids didn't know a frumpy middle-aged woman knew anything about statistics), I'll explain it so that everybody who doesn't already know better can understand it.
Suppose that it
was possible to make 3 billion a week. Or, since the author has backed off and said "up to 3 billion" per week, we'll go for 2 billion a week.
2 billion a week is 2,000 chunks of 1-million-gold. A million gold sells for $5-6 on the various websites. Even before balanced trade, it sold for $4 or more each. If such a method was possible, people would know about it. That's not something that's going to be a secret of a few people. The Asian gold farmers would have figured it out ages ago. Instead of having their workers picking flax or fishing lobsters or cutting yews for 200k per hour, they would make the 25 million per hour (which is about what 2 billion a week is for 12 hour days every day). So now everybody is making 2 billion per week, everybody has 2,000 million-units to sell per week, and the gold farmers have more gold than they can sell. And the people who slave for these Asian gold moguls (and for very little per day) will now go into business for themselves, because they can make 2,000 million-units per week.
So what happens to the gold? The price goes waaaaaaaay down. To like 50 cents each million. Why does it go down? Because at $4, the supply is much greater than the demand. There are more competitors, and they will lower the price on each other. The market balances itself. 50 cents per million is still a cool thousand U.S. a week, which is big bucks to somebody who was making about $30 a week before. Now of course it isn't that simple, because the gold still has to be unloaded, and that takes time, but the point is clear enough.
And if all of that doesn't make sense, put it this way: If there were a way to make 2 billion a week, every week, that somebody with a level 100 account could do, then anal old Jagex, the good folks who brought you balanced trading, the Gross Exchange, the Tamederness, and the wonderful new Pest Non-Control, would have put a stop to it loooonnnnng ago.
So nopers, I don't see a way to make anywhere in the ballpark of 3 billion per week, and my offer of $500 ($10 up front) still stands. If it's legitimate, I won't be losing out on the deal. I'll make a lot more than that in gold sales before it gets patched---and I'll be making a lot of gold dealers very happy with $1 per million gold.
