Trading in platinum for gold/gold for platinum

[SuperGotenks]

Hey guys, just wanted to suggest that a section would be trading platinum for gold, like converting into gold or platinum. I think it would be better because its impossible to scam, and it helps players that cannot afford platinum with money. But on the other hand, it could wreck your profits. :/. That's just my idea.
2 platinum-2500 gold
5 platinum- 5000 gold
10 platinum 10000 gold
Something like that, lol.

Cheers, SuperGotenks.
