Unless a gem transaction on the trading post takes away 15% of the coins and 15% of the gems, then only the gem seller is paying the tax (the gem buyer receives 100% of the gems that the seller pays). That means that one full buy/sell cycle only loses you 15%--the world as a whole has lost 30%, but half of that was paid by someone else.

Example: Suppose that 100 gems are sold for 10 silver. Alice pays 10 silver and receives 100 gems, Bob pays 100 gems and receives 8.5 silver. Alice then takes those same 100 gems and sells them for the same price--receiving 8.5 silver, just like Bob received for his 100 gems. Thus, Alice started with 10 silver and ended with 8.5 silver--a 15% loss.

Another way of thinking of it: in each transaction, there are 2 parties, but only one 15% tax. That means that the average tax per person involved is only 7.5% (15% split between 2 people). --Felbryn 06:28, 31 October 2012 (UTC)

I checked the TP just now. It costs me ~85s to buy 100, yet I can sell 100 for ~60s. The change from 85 to 60 is 25, which is about a 29% loss. So, while what you're saying does make sense, I think the TP acts as if gems must be bought for 115% of their 'price' and sold for 85% of that 'price'. Or maybe its just easier to say the tax is 30% rather than 15%. N Sejick 06:38, 31 October 2012 (UTC)

OK, it's possible that of the two numbers, I changed the wrong one... --Felbryn 07:11, 31 October 2012 (UTC)

Also, minor note: buying at 115% of the "base price" and selling at 85% would actually be closer to a 35% markup, not 30% (115 / 85 ~= 1.35).

I've reworded the paragraph in question. Better? --Felbryn 07:23, 31 October 2012 (UTC)
