Hi, when you check a bounty campaign and seems good and legit, white paper is cleanly presented, token price is good...
 but what's make you decide not to join and look for another?   

-for me if I saw the campaign is the same with the name of the manager, for example:

[ICO] [Bounty] DryMeat - $50,000.00 awards waiting
Campaign Manager: DryMeat
                                      Copper Member
                                      Jr. Member/Member

When I saw like this then, I just turn around and look for another.
I'm not saying they are scam but in my side there is a possibility, since they can just pop out and never bother using the account again.
What's make you not to join? Share it for the new members know.

Just come to my mind:

If IPhone developer and company enters bitcoin world and create their own coin,  releases iPhone product and products will be only purchase using IPHn Coin.

Do you think bloody things will happen?
