I got an idea for a method more complex that requires 8 sythe members that have been in the community for verry long and are verry trusted to work together + the buyer and seller...
Here is how it's done.
The gold seller Buys items that sell for an exact price (Like torags hammers : around 100k ea) or Whips for 1.2m ea.
He buys the same amount the gold that he is selling is worth.(let's say 10 whips for 12m)
8 Middlemen (I know it sounds silly but it's required.) meet up with the Gold seller and Gold buyer.
They enter a verry unpopulated bounty hunter world and all enter in a bounty hunter section (let's say 55-100)
Gold buyer pays the gold seller before he is killing/while he is killing/after he killed (not recomended) for the gold then kills him.
~Note: IF THE GOLD BUYER - failed to pay,refused to pay,attepmts to scam,the mods can pile him thus ending the trade process~
After the gold buyer gets the 10 whips,they all exit bounty hunter and go grand exchange.
The gold buyer sells the whips for 1.2m each (same price as gold seller bought) while they either get bought by someone else or they get bought back by gold seller (so,in retrospective,he lost nothing).
This,imo,is the easyest way to trade .
Here,let's recap if you haven't got the idea.
1)GPsell
2)GPbuy
3)MM
4)MM
...
10)MM
They enter bounty hunter.
GPbuy sends lets say 50$ to GPsell for the money.
GPsell lets player kill him for his whips.
GPbuy gets 10 whips.
GPbuy and GPsell go G.E.
GPbuy sells 10 whips for 1.2m ea,getting 12m whilst doing so.
GPsell buys the 10 whips for 1.2m ea in grand exchange (thus changing from items to gold,which is that GPbuyer wanted.)
Everyone is happy.
I also suggest Sythe names a few persons and a new rank if this will ever be imposed,also,sythe gp sell events,like :
Friday :
12:00PM-13:00PM / world 65 /Bounty hunter gp sell : Mods assigned : X,y,z...
Gp buyers/sellers : X and Y,T and U....etc.
The trades should be done one after a nother so they can all be done at the same time,instead of getting intrerupted on a later note by a clan or something.
Hmm...
