Thanks o_e_l_e_o, after the extended discussion between you and Op, I have gotten a clear hint of how the project works.
Hi, I'm one of the reviewers in your Review Campaign, I have to ask whether you are shouldering the 2 USD payment for creating a safe? I don't mind paying for it myself but I have to make sure that there's an option that you will be able to shoulder the payment. I'm currently checking it right now and that's the only part that I'm stuck.
What do you mean by shouldering the payment of 2 USD. If you are accepted for the review campaign, btc upto 0.003 or so would be sent to you and that will be enough to shoulder whatever payment and also compensate your efforts.
