Bitcoin-Central.net now supports Pecunix gold trading.
Users can add Pecunix gold grams to their accounts, from there they can trade them for free for BTC, and send them for free to other BC accounts (sending to e-mail addresses in progress
).
And of course, it's completely open source.
Withdrawing gold will be manual unless I manage to get Pecunix to activate the API for Bitcoin Central.
Thanks a lot to jgarzik for his bounty (
original thread) and the 2 grams I borrowed from him for testing purposes!
