1. The bounty has been running from July last year.
2. Payments are made monthly and have been in time without any problems.
3. Payments are made in GOLD Token but you can trade it off as soon as you want from their marketplace for BTC or ETH if you wish to.
4. The Gold Token is a stablecoin pegged to the Gold price so their no dumping in the token value like other bounty tokens where they end up being worthless
IMO this is one of the best altcoin bounties in the recent times.
However, this project seems no longer accepting for new participants, it has a limited number of allowed participants so even if it is included on the list, other participants can't even participate due to this reason. I have been seeing that project since december because I want to participate but sadly they don't add for new participants.
