Hey,
I just want to put in my 2 cents here since we're right now doing a bounty campaign.
1) Point 1: Paying only if successful - because we didn't want there to be any misunderstanding, we wrote up front that if we pay out only if we reach a minimum level. Like that each person can decide if it's worth it for them or not and for us, we know that those that do sign up are serious about what they're doing.
2) Point 2: Worth of coins - since the coins are pegged to the IDXUSD (the tradable diamond index) and since the majority of the funds will be used to purchase actual diamonds so that the value of the diamonds is worth the value of the coins, then there is no question of the coins being worth something.
In case anyone serious is interested, here's the link to the bounty campaign:
