Thank you @enjar. I think pulled data of transactions can show the unique number of users and how many times the same users received the torch.

Your questions and @bengy's comment made me think maybe it shouldn't be about money and rules should change as follows:

• Initial amount of 10 Steem.
• Torch keepers can either add only 1 Steem or nothing.
• At 10K count (or higher milestone) burn the total by sending to @null
