Precisely.
I can understand the Real World Money side of this equation for you.
My comment was more about “why has the gold value gone down and not up” and the simple answer is:
1 Money supply has dropped - the gold mill that was the mission boards has been beaten to heck and gold from wq’s and other sources is lower as well
2 Were not in the expansion end lull where people were paying for M+ carries and guild runs as much (not saying not at all, just not as much)
3 More players have disposable income (overall that is; the economy is not better everywhere but it tends to be in areas with higher gamer % of population) and therefore more are able to purchase tokens to get some gold (THIS IS OF COURSE IMHO).
These factors are driving down the price, or rather keeping it stable for now.
they wont stay stable at over 150k.
Not until there is a content drought at end of x-pac (this always drives em up as nobody is buying them with real $)
any increase is short lived as its a new content bit. likely wont last a month.
The best part of your analogy is that every time you think about the price of the item and the gold price of the item, no matter how it is bought, Blizzard makes money.
Some people bought the pig in the store day 1 for real money.
Some people converted gold to wow tokens to battle net balance to buy the pig in the store. To do that someone else spent real money and received gold back as a result.
And different people will value that token price at different rates. For you it might be 300k per token.
But you may never ever get to that point, as hordes of people may jump on the price at 250k, never permitting it to rise over that amount. Just as there are many people that would jump at 200k, and lots at 150k.
I would suggest taking a macro economics course. Or just looking up supply and demand.
